Wavenet (using Tensorflow) showing '2 steps together' after restarting previous training

Only having trained once before, my output was about 1,115 sec/step and "files length: 1" was displayed after every step.

I stopped the training, and restarted it using the "-restore_from=/logdir/train/..." option, the output is now a bit different.

It almost seems like it is taking 2 steps together somehow, but I don't understand enough about what could potentially be happening.

Should I adjust something, or is everything fine even though the steps look so different?

Many thanks!
