Venstar 2491T Insteon v.93 thermostat through ISY994 can't set temps on Home Assistant

I have two thermostats (upstairs and downstairs) going to my ISY and everything works properly on the ISY console. I then added the ISY to my new Home Assistant installation and everything is working except for setting the temps on my thermostats. It shows me all of the information properly and updates on the Home Assistant dashboard when I make changes on the front of the unit, but when I try to set a temp on the Home Assistant dashboard (webpage) for either thermostat, the set temperature snaps back to what it was before and I get the following in the logs:

Failed to set heat setpoint on 14 66 33 1, it is not a thermostat node.

I’m new to Home Assistant so I’m not sure what other information you may need, but I have provided some below. Any help would be greatly appreciated.

Thermostats: Venstar 2491T Insteon v.93 thermostat (both are the same)
ISY: ISY994 running firmware V5.3.0
Home Assistant 2021.10.5 (Operating System version 6.5) running on Unraid (through VM)
Integration: Universal Devices ISY994 - Home Assistant
