@abundant-dinner-65974 Thanks for the report. Known issue, we’ll be looking to fix it in the next release. We issued a hotfix yesterday, but that broke the Edit layout screen on Stacker Classic. We had to revert the fix and get back to the drawing board. We think we have it ready, but it will need to go through more QA this time around.

Thanks Seb

You might be able to temporarily fix this with custom CSS, though I can’t guarantee that there won’t be any issues. I haven’t had a chance to test this with every combination yet.

.css-rlg1ny {
width: 100%;
margin-left: 0px;
}

that's what I have in my custom CSS ^ and it's worked thus far with no issue
