I just had a bug when I tried to copy a username or password by clicking on "copy" within 1PW8, it didn't copy the content to the clipboard although the notification said so.
After restarting 1PW8 (and just the app), the function worked again. I have seen this thread with a similar problem.
Just wanted to let you know in case it hasn't been reported. Let me know if I can be of further assistance.
