Button Click opens new modal


I created a new website (it’s my first one, so the structure is probably not best practice).
On the website I have different modals which include close buttons. For every modal the close button is working fine except from the modal “Modal Hotel MRU - done” (talking about Button 4 in Div Block 7 in this modal, desktop version). Depending on where I click the button, either the interaction works as planned (the modal closes) or another random modal is showing up. Same is for mobile version (Div Block 8, close button mobile).

I can’t find the issue and would be very thankful for your help.
