Upfront broken after latest update

Hi,
I applied the latest update for Upfront and some websites using Issue theme or a theme created with builder are having issues, I am unable to add regions :slight_frown:
The green button with the gear doent show up at all, I tried resetting upfront cache but it did not make a difference, the issue appears to be only on the front page. any assistance would be greatly appreciated.

Thanks,
