Core one PEI Sheet became bumpy after trying atemperature tower for ASA

So i wanted to do some filament calibration for some leftover stratasys ASA and when i remove the PEI plate, i noticed that the side of the sheet that was in contact with the heatbed became bumpy.
Both sides also got the bubbles.

Im not sure how visible the bumps in the image are

I used this upload for the tower (core one, standard nozzle, ASA): https://www.printables.com/model/39810-improved-all-in-one-temperature-and-bridging-tower/files

Anyway, is this expected to happen or did i do something wrong?

This is normal behavior for the adhesive film.

For ASA, I would recommend using a textured or satin printing plate.

how much does it affect adhesion of prints with pla, petg or abs?

also is there any information on prusas website that i didnt see?
on their printplate maintenance site where they list what materials work with what printplates, it just said use gluesticka
