LibreOffice Calc pastes as image rather than text/formula

Hi there, think this is similar to How to stop Calc pasting copied cells as images

Sometimes (about 30% of the time) when I do a Ctrl-C/P or X/P or use the Edit/Copy Edit/Paste menu, I get an image of what I copied pasted, not the actual text/formula.

It happens in both W10 and W11. Any idea what I’m doing that causes this?

Thanks,

Thane
