DHTMLX Grid #stat_totals are wrong after filtering - dhtmlx

Question

I have a grid that is loaded via JSON / ajax that has a combination of filters and stat counters in the header area.
The stat counters seem to work correctly until one of the filters are used, and then the numbers in the counts are off. Sometimes off by 1 or 2 others by 5 or 8 or 10 even.
I am having a hard time trying to debug this library and was hoping someone else has ran into the same issue and can point me in the right direction.
I am including my full grid setup, but if you need all of it, please let me know.
Sorry in advance, this formatting is not very good.
Thanks
