Dashboard UI Undefined

Hello,
I have been working with a dashboard I created on a Windows 10 machine for quite some time without issue. I tried to run a second instance on a different port to try some new ideas without altering my original flow and in the process somehow broke my dashboard. Node red starts without error but the ui shows up as a tab named undefined. This is only the case in google chrome browser, it works in Firefox, and IE11, but crashes when used. It never crashed in Chrome. I have tried wiping node-red and reinstalling but get the same undefined issue. Can someone please help to resolve the issue?

Thanks,
Dave

How are you generating another Dashboard? Node-RED only supports 1 Dashboard per instance of Node-RED.

I am not trying to run 2 dashboards. I was trying to run two instances on different ports.
