I just noticed that the tooltips on the UI Builder component sidebar are all showing “undefined”. I have used these quite a bit to get my bearings, and assume others have as well so thought I would let you know. And I even checked in multiple browsers this time!

Hi Roger,
Looks like a regression. We’re looking into it (internal ticket is BKNDLSS-28348

Hello @Roger_Quennell
We’ve just updated cloud servers with a fix for the issue you described above. Could you kindly let us know whether fix works for you well?

The “Repeater” labels tooltip says “dynamic list behavior” the others I looked at still say “undefined”.
The “Repeater” says that intentionally since the “Dynamic List Behavior” field had been renamed to Repeater. This way others can identify what it is. For all others, I am not getting any tooltips, which is the expected behavior (checked in Chrome and Firefox).
In what browser do you get “undefined”?
