Bubbles on iPad Air 3 AFTER lifting screen protector

I have recently got the new 10.5 iPad and finally received the screen protectors I bought on Amazon (amFilm by TECHmatte). I had so many bubble I decided to lift it partially away so that I can lower it slowly and see if that would help, as the included card was of no help. But I noticed that the exposed iPad display retained the imprint of the bubbles! If I touch one of thos "bubbles" they move and split and recompose themselves when the finger is lifted. Has the display been damaged? I am absolutely mad. I have never experienced this before. Before the iPad I protected my iPhone 11 Pro Max with a different brand without any issues. Please help!
