I am able to replicate this here on meta, on a variety of themes so not theme specific. Select posts to move via admin wrench, select move to another topic, select existing topic, type in keywords - get suggested topics to move to but without any title. Still works if you choose by topic ID but a bit handicapping.
This is also happening on my forum. Lists several choice, but no names.
So this is a theme color scheme mistake of some kind @awesomerobot
Looks like the topic title is missing entirely, investigating…
I’ve got a fix in here:
@tgxworld stripped out some attributes in search (PERF: Reduce size of search payload by removing unused topic attributes. · discourse/discourse@84de643 · GitHub) so I had to switch
Hooray, fixed! Thanks so much!
