[Resolvido] Issue with trnalsations beeing removed

Background of the issue:
I am using WPML with my website link oculto. I have used WPML a lot for different websites and am somewhat familiar with it.

Symptoms:
Not all of my content is showing up in the advanced translator, so I had to translate using Duplicate content. I have translated my website a few weeks ago, but some translations disappeared. I redid some translations, but they disappeared again. I can't find some of the strings from the theme.

Questions:
Why are some translations disappearing after being redone?
Why is not all content showing up in the advanced translator?
How can I find missing strings from the theme?
