Can’t set background color in individual cells

[laguna]

LibreOffice 7.4.7.2, OS Linux 6.1

I can’t set background color in individual cells. Sometimes I get color by double-clicking on a cell, but as soon as I click on another place, the background disappears. I tried also save .ods as .xlsx, but
calc-gaz.ods (13.4 KB)
no difference.

OK, I found the partial workaround: in Debian, Settings Manager > Appearance > Style had changed to “High Contrast”. Choosing anything else allow change the cell background colors. But changing back to “High Contrast” destroys the cell colors again.

Some of the cells are altered (direct formatting and style formatting). Can you recognize the altered backgrounds?

Is this question connected to your question in

?

Yes, I can see cell colors backgrounds in your file. But only when in Debian, Settings Manager > Appearance > Style is in a different position than “High Contrast”. I don’t think if I can use calculator without direct formatting and style formatting, so yes, cells will be altered.

No direct relation to my another question though.
