Thanks for reaching out and sorry for the trouble. This isn’t expected behavior in Adobe Express. Could you let us know if you’re working on the web version or the mobile app, and share your device/browser details? In the meantime, please try updating to the latest version, clearing your browser cache (if on web), or reinstalling the app (if on mobile).
If the issue continues, it would be very helpful if you could share a screen recording of the problem. This will allow us to try reproducing the behavior on our side and speed up the investigation.
