[Closed] Translation Manager / Cue vs String Translation

Dear WPML-Team, I am trying to translate my englisch content of hidden link into Portuguese and German. I spent the whole day doing so editing using the Translations Cue. Now in the cue some show status "complete" (I think I did some translations a wile ago already). Some show status "in Progress", but when I click on translate they are on 100% and when I click on "complete translation" they still show up as "in progress" in the cue. Then there are some entries with (no title) as title and when I click on edit the page then does not stop loading (freezes) until I hit the back button. The homepage has the status "completed - needs update" but when I click on edit->translate I receive an error message "WPML tried to translate this page three times and failed. To get it fixed, contact WPML support".
Thats what I do now.

Also on the translated pages until now the layout seems to be disrupted by the translations or its because the I have translated the page, but not all widgets used on that page...?

I have already found that lots of the content I would like to translate seems to be hosted by the themes (shaka theme by proteusthemes) widgets and I fear its only possible to translate these using the sting translation. The problem here is, that the text fields contain also HTML markup, which makes it very difficult to read and translate (also using automation).
In that case it would be easier for me, instead of editing each string /block of text being annoyed by HTML markup (potentially causing errors on change), editing each page not using the WPML Translation Manager/Tool.
Any advice on best practice?
What would be the most efficient way to go from here?

Attached you find a screenshot of the last few entries of wpmls error log.
Is there some conflict with the staging site?
Is this causing issues?

Kind regards, Jens
