@FoSuCloud Thank you for opening this! If you check out the code for #15948, which changes the widths of columns to allow them to flex, do you still see this behavior?

[FoSuCloud]

Thanks, I can see that the "last modified" is no longer overwritten in the code branch environment of #15948.
I will close this issue after the PR is merged
