Anti-slip pad destroys foamed dashboard

Greetings! I have the following problem: I bought such a mumbi anti-slip pad story for my girlfriend’s 1er BMW. The thing was on the dashboard for three days. When we replaced it, we were terrified that the foamed board under it is sharply narrower than the rest. Now, four days, nothing has changed. Here’s a photo. Do you have a clever idea to fix it again? Best regards!
