Pastor manager will create a good password I paste it but then I'm stuck I can't repaste it to verify it

Everything works out on my passwords I’m just trying to change my passwords it creates a password I’m able to put it down once then that’s it and I don’t know what the password is so I can’t change the password or anything

Is this when you are trying to log into a specific website? If so, I have run across websites that do not allow pasting into login/password boxes.
