I/O Settings won't reset to Default

[Brightbelt]

Hello,
I'm on a new iMac Pro with 10.14.6 MoJave and I configure with an Apollo UAD2 Thunderbolt Interface.

I configure the UAD2 by going into the Pro Tools I/O Settings - and I delete the current I/O paths - and then I reset the Input, Output and Bus tabs to their Default settings.

And I've done this several times so I know how it's supposed to work. And now, I get only one Out 1-2 path for my Input and Output tabs - and they don't reset to the default settings.

The Bus tab has a whole list of stuff I can't decipher. It DOES reset to default correctly. But that's all.

I appreciate any help on this. FYI, I have searched the forums; I have engaged Avid Incident Pay tech support, and Universal Audio Tech support.

I appreciate any help...Thanks !!
