Freezing tire temperature only works on front wheels of many mods

Sorry to bother you about yet another thing, but as topic states there seems to be an issue with the tire temperature lock for a lot of mods where it only works on the front wheels. One example is the STELLAR K61 (3A9). On the attached image I tried to lock the tire temperature at 60, then went into the garage and increased the tire warmer to 120. When going back onto track only the front tire temperature is locked on the K61 (same when driving), but for the VSI-V2000 (99D) it works on both front and rear.

Wondering if this is fixable. Is the rear tire temperature stored at a different memory address for some mods perhaps?
