Using bootstrap sampling to generate a bunch of different trees is the essence of random forests. Having the option (useSampleBagging) to turn it off is uncommon, but defaulting to false is super odd.
I also increased the number of trees. On R the default is 500, on python i think it is 100. I don't know, why the default here was 10 (perfomance?), but that is usually not enough.
