Hi,
Noticed that when you use a block with a border width and border style and then add another element (the first element added only) into that Block then UI Builder looses the border style for that block. It comes back if you reselect the border style or refresh the page. Seems like a bug.
Thanks for the report. I was able to reproduce the problem. Internal ticket BKNDLSS-28882 created.
We will let you know when the problem has been fixed.
Thank you for letting me know. I have tested the issue and the bug is not there now. Functionality is working fine.
Appreciate the team updating UI Builder.
Thank you
