Not working as expected

I’m seeing this annoying popup every few minutes after installing the Pro version of the plugin which keeps me out of WP dashboard even if logout feature is disabled for Admin in the plugin settings. Any idea why is this happening? The issue even exist when the plugin is deactivated unless database of the Pro plugin is manually removed (for some reason there is no option to automatically remove all plugin files after deactivation so this has to be done manually). See the link below for more details of the issue. Thank you!
