I have login saved for this site, but no suggestion if I use 1p mini, it works before the 7.3 upgrade.
besides, "打开并填写" works.
1Password Version: 7.3

OS Version: 10.14.5

I've been able to reproduce and after a bit of discussion with a couple of the developers we've located the cause. Until we can determine how best to fix this I'm afraid the best workaround I've found is to search for your Login item. Once you locate it you will find the button does display AutoFill and it will fill the page.
I do apologise that it isn't anywhere near as seamless as it ought to be and I can only hope we can get this improved on promptly.
thanks, hope so!
