You're not the only one!
Other than your salt and CH being a little low I don't see anything else wrong.
CH doesn't matter to a vinyl pool but I wonder if it being low has anything to do with it?
I'd suggest doing an OCLT (overnight chlorine lost test) but I'm not sure you can with the kit you have.
