changing settings does not work

[fratopa]

I just tried to modify the standard settings for this package by going to /rgbd_localization/src/find-object/include/find_object/settings.h. However, changing the maximum number of features from 500 to 10000 in the default ORB parameters yields no result in the number of features being tracked, as far as they are reported in the GUI. Btw i assumed the system is using ORB at the moment since this is being reported from the GUI as well.
I believe I am doing something wrong, could someone point me towards the correct file to use in order to change the default settings?
