Rule against selling paper from CPD stock?

Our store got a new GM from another store last spring. She keeps dropping new rules on us that she says have been in place for years and I'm trying to find out if she's pulling them out of her ass or she's following the rules.

Has anyone heard that we can't sell paper from our CPD stock if a customer wants to use it at self serve? I understand if they want to buy 200 sheets when they can buy a ream of the shelf, but she won't let us sell a single sheet anymore. It's honestly pissing off customers and we're losing more and more everyday with her bs strict rules.
