Autofill for subdomains broken

Hey Dave! 

Thanks for your kind reply! 
I double-checked the autofill behavior - see the screenshot. 
More general info on this: 
- So far I only noticed this with this one login, but it might be the only one with different subdomains. 
- It used to work. I have been using this login with different subdomains for a long time. 

Do you have more than one website address added to this item?
I did not when the problem first occurred. I added another subdomain and that solved it for that specific subdomain. 

Is the item suggested on the page and it's just not being filled properly?
No, it is not suggested at all. 

What if you add the exact subdomain that you're trying to fill on to the login item then does the item fill correctly? 
Yes - for that specific subdomain.
