Hi! I'm using Enpass Desktop Version 6.7.2 (886), Extension Version 6.6.2 for Chrome, Brave and FireFox. Occurs on my Windows 10 desktop and laptop.
This happens to me on multiple devices with Brave, Chrome, and Firefox with Windows 10 for all websites. I go to the website, click the browser extension icon, click on the account to fill, and it opens a new tab. If I close the new tab and try again, it autofills correctly.
