wow, thanks for taking care of this. I had no idea the problem wasn’t as clear from the OP’s initial message.
As for the ‘set initial size’, devs usually put it somewhere in a menu (where you can also set a fixed % size), often even into the preset menu. Not the best UX though. I’d think, for symmetry reasons, putting a button for fixed resize and a ‘set as default size’ options to the left of the preset menu could work well without trashing your interface.
Yes, I am on Windows. Happening with Live 11 Suite, also the Beta. Haven’t tried the VST2 version, as I prefer using VST3 and only bothered to install this.
