I should note, I'm no longer using the Docker Desktop Extension of Portainer, this bug is simply running the standard Portainer CE image within docker desktop.

Thanks @jamescarppe not a biggie, but certainly unexpected.
@jamescarppe I can confirm it's related to colour. If you type "export TERM=vt220" you'll turn off the colour and the underscores will render. It is caused by the fonts used...
@jamescarppe confirmed the fix works. I'll create a PR if I have some time. 
It would be nice if this could be made easily configurable for any upstream ranges I want.
I already feel that the trust is too wide.
