Conext MTTP 60 150 display issue

One of my fairly new MTTP 60 150 charge controllers is having a weird issue with the display... it's showing the "SYSTEM" values but keeps flashing "OUTPUT" briefly and won't let me scroll to the INPUT display without hitting the down button a bunch of times in succession. Then it only stays on the INPUT display for a second before reverting back to SYSTEM. This is hard to describe so here is a video showing the strange behavior:

My other MTTP60 doesn't do this and I've tried copying the settings from the working unit but no change. I've had some recent issues with my system when I added a Gateway (see my other post). This display issue is a new one.
Any ideas?

Comments
- Kill solar panel power first
- Kill DC power to charge controller and wait 5 minutes
- Reconnect charge controller to DC bus and let boot
- Reconnect solar array
And the other classic--Reset to factory defaults, power down as above, reboot and reconfigure/save configuration.It is not unheard of for a software upgrade to get confused/not upgrade a database from an earlier software release--The factory default/reconfigure can fix these.

Taking a break from the 91 degree FL sunshine/heat while moving 4kW of ground mounted panels from staging area out to my field for the MTTP100 (4 x (4 x 250w)).

... just 3 more to go!!!

For permanent structures--You probably have local codes on designs and possibly even "wet stamp" engineering design drawings requirements for mounting the array.
Depending on brand/model/frames/mounting, panels can be rated from 50 to >200 lbs per sq foot (wind/snow/etc.).

It is only my opinion that these are NOT permanent structures in as much as a portable generator is a permanent structure. I am in dialog with the county engineers to determine how these racks will be categorized and what uplift mitigation requirements will be needed.
Just want to make sure you are safe and don't get blindsided by local inspectors and their requirements.
Have fun,
