What can be causing a negative cooling load on VRF systems on Doas?

edit

I have a peculiar HVAC system on an OS 3.2 model which integrates 2 condensing VRF units and independent vrf sistems connected to the DOAS loops. I modeled the system using ladybug tools. When run, the simulation shows a large negative load for cooling.

Would you know what could be causing this? I am attaching idf and osm files in case anyone could please have a look.
