Passwords not copying - please, I'm desperate!

Hi,
I and another collegue of me has similar problems.
We use the 1Password for windows (desktop app). We use Oracle VM virtualbox manager to make connections to VM's and from there make connections to other servers.
The password copy (by clicking the copy button in 1 password, or using the quick key setting in 1 password to copy the password) sometimes doesn't work. If it do paste something, it's the last text copy that is stored in the clipboard.
My workaround to make it work is:
1) copy a random character or word or whatever on your local laptop.
2) copy the password from the 1 Password entry
3) now you can paste it everywhere you want (local, VM,...). The correct password is copied to the clipboard.

This workaround always works, but it's so annoying that way. I think 1password is a very good password manager and I'm glad we use it for the whole company. But there needs to be a solution for this.

My windows version and 1 password version see below:

windows 10 pro
1Password for windows 8.10.1
