Checking and Unchecking Tasks in Tasks Query

Hi everyone,

What I’m trying to do

I set up a new PC with a fresh Obsidian and found that my vault acts differently than before regarding Tasks queries. I am unable to check or uncheck tasks in queries from the Tasks community plugin. (as in GIF: upper tasks are original text, lower are query)
checking

Things I have tried

I have looked for relevant settings without success.

Your help is very welcome. Thank you !!
Best
