Has this scheduling option been deactivated? Classes: Allow clients to book multiple spots

I'm trying out Scheduling and I don't see this option anymore on the Scheduling Page Options menu. Is this option no longer available?

Nevermind! The option wasn't showing there before, and now it is.

I'm glad it's there now but doesn't make me too confident in a system where menus might not always be consistent every time I log into the system.

I expected the platform to have a better user experience. As a former software engineer and small biz owner, not impressed so far.
