Two identical WD Myclouds - Infuse only sees one

I have two identical WD MyClouds in my system.

When I try to add shares, one of them shows up as both ‘WDMyCloud’ and it’s IP address, the other one only shows up with it’s IP address.

When I click on the IP address of the second one, it can’t be added as a share. Are there any settings I am likely to be missing? I can log into them both from my Mac and PC.

Do each mycloud have unique host names? Some devices can be picky with devices that aren’t uniquely named.
