UX Issue with Relume's Contact Modal on Webflow

Hello everyone, I've been using Relume's Contact Modal 1 on Webflow, but I'm having UX problems. When you click on the “Contact” button, the modal opens. The form works. However, if I close the modal, it's as if it went into the background and blocked the interface (see video capture). Has anyone encountered this problem before? Have I set something wrong? Thank you for your help 🫶🏼 Have a nice day, Louis
