this is under H2O Flow webinteface. For deep learning grid search and single model search. The "overwrite_with_best_model" is sometimes missing or true/false switches.
If the button is clicked it is sometimes turn on in the flow command, see below:
But then in the the grid search results for the individual models it is turned off
Then on the next grid search the option button disappears or it sometimes comes back,
This usually happens after multiple rounds of turning grid search on and off, running single models and the other deep learning models.
this version 184.108.40.206 has issues during grid search including not showing correct values in the final grid (another ticket).
