Center container on Webpage

Running 2025r2.1 and all of a sudden, I don’t seem to be able to center a container on a webpage.

Previously, I was able to just lock the center padlock and it would center the container on the webpage, but now I am unable to just lock the center padlock in the locking segment for the container.

Any ideas?

Could you please share a sample project showing what you’ve been already trying?

I don’t see a center padlock, only top, left, right, bottom. Can you share a screenshot?

I have this:

that works correctly (center of the page).

Note: I have seen 1 report that someone was not able to unselect all locks, but then a restart fixed that problem.

Rebooted computer and all is good. WTH?
