Shouldn't I see a button?

Shouldn't I see a button?

Newbe here,

Going through the steps to test out BDRSuite. Adding a repository it says it can do NFS but all examples are SMB... And! There is no "Add network button" it's just a blank white space, but the mouse over description is still there. 

Yes, I tried a different browser.
Yes, I have nfs-common intalled, no I don't SMB or CIFS is not installed.

Yes, I often feel like the simulation I live in is under resourced and things are being left out.
