UPN mapping errors when using Enterprise Gateway

[Kobe24]

I've got these when I try to set up the UPN mapping rules in the data source using Enterprise Gateway. Any ideas? 

Thanks

hi @Kobe24,
Does trying again resolve the issue? Sometimes issues gets resolved once you refresh the browser, did that work? 

How many mappings do you have?

I was adding the first one. I tried many times at work (win7+chrome) and it was not working. I tried at home (win10+Edge) and it worked. Wierd, but thank you
