PatchTSTForPrediction outputs

Hello there again, why does the PatchTSTForPrediction return touple during inference that contains 3 tensors?? If for a batch i need only one such tensor ? cause the tensor is of size [batch_size, prediction_length, num_input_channels] but why generate 3 such tensors?? Do i need to avg them or whatsup with that.
Thanks for the response guys.
