Multihead classification training bug

Guys I having trouble training a multihead classification model. The first two times the training went well. I added a couple more images and generated a new dataset. I tried to training 3 times with tree different models, the training concludes but the metrics seems to bee messed up, and the model does not classify new images.
Thanks in advance guys
