Dish pro switch problems

[mad satter]

Hi all, newbie here.
I have a dual LNB Dish pro 500 with 2 receivers (both models are DP311). One receiver is working great, with both sats displaying very
strong signals (115+).

Problem:
The other receiver seems to have lost sat 110.
When I open the 'Installation Summary' page, I see only sat 119 under dish input #1
I can't seem to figure what happened to dish input #2 or satellite 110. Nothing is there.
Somehow dish input #2 got up and left the building and took sat 110 with it.
Below is what the summary page displays.
Shows nothing about Input #2 or sat 110 at all.

Input: 1
Satellite: 119
Device: All (should be 'Twin'?)
Status: Satellite reception verified.

I tried hard booting the receiver to no avail.
Ran switch check, OK.
Have any of you encountered something like this?

Thanks for reading this.

Will check back tomorrow.
Good night all.
