Probably fixed in https://invent.kde.org/education/labplot/-/merge_requests/217/ Can you test with the current stable version 2.10 or the nightly version?
I was able to reproduce your problem also in 2.10 with your project. If I recreate the worksheet, the problem does not exist anymore. So as a workaround, please install a version later than 2.10 and recreate the plot
I've since downloaded 2.10.0 and the issue persists in new project files. I'll download 2.10.1 and report back.
I was able to reproduce in master, I will check it out next days
