I don't seem to be able to reproduce that issue. Could you please provide a screenshot or string with the blueprint folder affected?

Indeed not as easy to reproduce as I thought at first, sorry.
I've managed to reproduce when I've dragged several blueprints deep inside folders up a level and then back into the folder. Try changing individual blueprints locations in terms of folders.

Thanks for your blueprint. Unfortunately, I still can't reproduce it. This seems to be some race-condition happening when the tooltip's text is measured.
