Tell us what you are trying to do?
First i have a trouble with otgs tools (popover , switcher) in wp-admin, but it's solved now.
Then if i want to translate page (for example covid-19 in advanced translation editor i see that target lang and source lang is null). By clicking finish job i get message "complete, null" on green background.
Second issue is about not displaying all custom fields for translating (main page for example).
If possible please share a screenshot of the null source language and "complete,null" results , also please let me know which custom fields are not showing.
While you are in the default language's edit page, scroll down to Multilingual Content Setup and click on "Show system fields", please share a screenshot of these fields with me as well, as some of your custom fields might be set to "copy" or "do not translate".
4 - fields of main page in advanced translation editor (not all fields)
5 - system fields set to translate
P.s.
Problem with fields that are no showing. Maybe i need to refresh translation page in some way, because when i add new english translation , all fields are displayed.
Yes for the fields that are not showing I can see that they are correctly set up in the Multilingual Content Settings, if you make a small change in the default language or update it then they should show up in the translation.
For the issue with the null source and target languages I would like to request temporary access (wp-admin and FTP) to your site to test the issue.
(preferably to a test site where the problem has been replicated if possible)
**Before we proceed I recommend taking FULL BACKUP of your database and your website.**
I often use the Duplicator plugin for this purpose: http://wordpress.org/plugins/duplicator/

a part of the problem is solved, but it still display null by clicking "complete" button (screenshot 2). Finally the main issue is that the language switching does not work. If I choose English, the page was still in Polish (screenshot 3).
I will look into the 'null' part when finishing the page, as that part does not have to do with the language rather it usually just shows a success string saying "Translation Completed" but let's make sure the language switching issue is resolved.
Your site is built with ACF groups, therefore I highly recommend to review the following documentation.
Your ACF groups were set to "Translatable" , instead they need to be set to "Not Translatable" as explained in the above documentation, and controlled from within the pages or posts under the Multilingual Content Setup (Pages->Edit Pages->Mutlilingual Content Setup) for each field.
However, the main issue that I see here is that the ACF fields for Contact come with a default value. For example, go to the edit page and edit the Title field in the Polish language.
hidden link
Notice I have added TEST at the end of the title, this does not show in the frontend of the Polish language.
hidden link
The same results happen if you create a new page, assign the Contact fields to it and then fill it in with test Title and Address they will be overwritten, this issue happens without WPML activated as well.
If you use WPML Advanced Translation Editor in any other page that is not using the ACF template its working as expected.
So, problem in my case was in custom fields displaying method. I have used get_post_meta() function with field id. Instead i need to use just the_field() func, hidden link .
Now, language switching work very well. Thank you for your help!
