Languagetool on Libreoffice not working

I’ve followed the steps here

but after opening my document, no sentences are underlined in blue or green, only some words are underlined in red and it looks as if that is the standard Libreoffice spellchecker and not Languagetool.

In my documents, the text is split into a table where I have a source language on the left and a target language on the right. With previous versions Languagetool had worked fine, then it stopped and I upgraded. After installation, it does not work.
Any ideas on how to solve this are welcome!

I have pretty much the exact same problem. I’ve double-checked all my settings and believe them to be correct. It was working, but one of the recent updates seemed to have broken it. As noted above, some of the words are lightly underlined in red and before, I would have left clicked on the word and seen the LT suggestion, but now, nothing…
