Repeater heights not adjusting to size of text / container tiles off track

When I first created my website with a repeater, I was able to have different sized containers depending on the size of text. Each container has unique content.

Recently, when I’ve gone to edit and add containers, they are all the same size in my Editor – even though the published version of my website has different sized containers. I have tried restoring my website to the last time it was published, but this still doesn’t fix the problem.

I can’t find a way to edit containers individually, any action seems to affect them all. The tiles of the entire repeater seem to be off track, with the tiles for the last container being off by almost an inch and half, and leaving a huge dead space at the bottom of my page that I can’t get rid of, because the tile extends so far past the actual content. How can I get my container tiles back on track and how do I get the size of each container to match the size of its individual text?

I’m incredibly frustrated and would appreciate help. Thanks!
