creating a new one and opening the package does the same thing, its the same on all stacks.
I have no doubt it's a MacOS thing, Im running MacOS 14.5 on a M2 chip if that helps at all.
I know I have managed to make an update like this before without this problem, its like the show contents now opens in read only mode regardless of what the settings are.
