Exported Model has less epoch than expected

[PavelPanjaya]

I've trained a model on a custom dataset and exported it with
python3 -m tools.export d23a69c5
I get a warning:
WARNING:__main__:Model d23a69c5 has less epoch than expected (0 / 10)

It's strange, as I know for sure the training finished successfully and I have 10 epoch in my log file:

My question is how do I fix it? Thanks.
