No Graphs on Newly Monitored Devices

I am monitoring 2 devices via SNMP and retrieving temperature data but the software is not generating any graphs for these two devices. I have other devices like these that I am monitoring and it is generating graphs for those. I recently upgraded to 12.0.1.

Any help would be appreciated since I need the graphs for these monitors

I am having the same issue, and there does not seem to be any consistency between the gateways as to why some have a graph and some don't.
