I'm seeing the same behavior in Cpanel v100.0.5 in the contact manager, under a single tab; "notifications". Select some or even all, and on saving (never leaving that same tab) and going back to that tab after, they're all unselected. It looks like the json file is being updated, based on the time stamp, but without being able to see what's been chosen it's not helpful to troubleshoot of I don't get an email about something and so on.
Any thoughts on what's going on there?
I also saw the same thing with backups when configuring those. Made all my choices, and on going back they were not saved. Configuring and saving a second time worked, but it's absurd having to go back and do everything twice (or more) with no indication it's worked.
