Autofill doesn't find correct Login

[eddie irvine]

Hi there,

I'm using a LG G6 with Android O installed.
I use the Android O autofill feature with Enpass 5.6.8.

When I enter a website (e.g. https://signin.ebay.de/ws/eBayISAPI.dll with Firefox Focus), I can choose "Autofill with Enpass",
But afterwards it always shows "autofill_matching_title_found", although I have a login stored exactly for this address.
If I do the same with the Enpass Browser it works.

What could be the reason why it never finds the correct stored login?

Thanks in advance!
