Auto-Correct Issues in Title

I am entering some new passwords ("Login" items) into my password manager account. I am having a really annoying issue with auto-correct. I often "title" a new password after the website (e.g. "myshop.com" instead of "My Shop"). Unfortunately, auto-correct is correcting the URL (e.g. "myshop.com" to "mishap.com"). Obviously, a URL is almost never going to be spelled like a singular normal word.

Now I have to pay close attention as I am entering these passwords, and I have to go back and check if the other ones I entered recently have errors. 

I am using 1Password via Safari on a Mac laptop. It is possible that this issue is separate from the 1password programming, but I haven't noticed this issue prior to now.
