Drone2Map does not convert Mavic 3T to temperature

Hello,

I am using Drone2Map 2024.2.1 together with the DJI camera add-on for thermal data from the Mavic 3T. I have successfully processed one set of data, but for another, D2M does not seem to be converting the data to temperature when creating a True Ortho. While the successful project has values of about -11C to +10C, the processed True Ortho for the second project only has values 1-254. When I use the DJI Thermal Analysis Tool 3 for the original images, I can see they have temperatures associated, so I imagine D2M should also see these. I also process them with the DJI tool to correct distance, humidity, emissivity, and reflected temperature, and try with these images, but I get the same result. 

I attached some sample images (only a few so the project is not too large, but the full imagery has the same effect). An interesting thing is that when I import them into D2M, I see that it does not recognize automatically that they are the Thermal images from the M3T, so I need to change this in the Edit Camera before processing. However, the results are the same either way. With the project that works properly, it does recognize that they are thermal images from the M3T. Could it just be there was a problem with the images when they were saved such that D2M is not recognizing them?

Thank you for any suggestions.

Paul
