Fleet does not plan correctly with a one commodity truck

In our current solution, we use 2 commodities for fleet planning, cold and ambient.
We have bi-temperature trucks with one cold compartment and one ambient compartment.
And we use the capacity usage to validate the correct amount of truck available per day.

Now we added one commodity truck, meaning that one truck can only transport cold and another one only ambient.

The problem is that when planning, the one commodity trucks are not taken into account.
Because OTM plan the shipments mixing commodities and when the capacity usage is checked, the shipment fails because the truck does not have all the commodities.
