OpenOffice & Extension Language Tool 6.0

I’m using OpenOffice 4.1.14 with the LanguageTool extension 6.0. Running on Mac & all in Spanish version

When in option: Tools / Grammar (LanguageTool) / Text review (F7)…

The “Ignore” function does not work. The LanguageTool window gets blocked.

This was working perfectly until approx. a week ago.

I’ve erased and installed both OpenOffice and the LanguageTool extension, and the problem persists.
Instead, if using OpenOffice without the LanguageTool 6.0 extension, grammar correction and the “ignore” function work perfectly. So, apparently, the problem seems to be in the LanguageTool 6.0 extension.

¿Any clue? Thanks
