Hi @NetWeb

Welcome to the forum! 
What Enpass version are you using? If you haven't tried the latest version 6.4, which is presently in Beta, please install Enpass Beta and check if the same issue persists.

After upgrading to 6.4 the bug is still presented. 

Hi @NetWeb

Sorry to hear that.

Could you please share your device detail along with OS version, so that we can help you better.

Thanks.

Its an iPohone XR iOS 13.5 ... still the same bug there. i got the newest app version.

Hey @NetWeb

Apologies for the inconvenience.

Please share the scenario in which items got duplicated before performing Auto-fill or it is always showing duplicate entry on your device?

Thanks.
