Cannot disable GPS on Edge 1040 from ConnectIQ application

In my application, I'm collecting distance, speed, etc. data from Activity.getActivityInfo(). At the start of the application, I'm enabling the GPS with 

Position.enableLocationEvents(Position.LOCATION_CONTINUOUS, method(:onPosition));

Later, if user select a certain config in the application, I'm trying to disable that with 

Position.enableLocationEvents(Position.LOCATION_DISABLE, method(:onPosition));

But that doesn't work. I'm still getting location data, and the distance and speed data all over the place: getting 1000000km of distance in no time.

I tried to workaround it by setting LOCATION_ONE_SHOT insted of LOCATION_DISABLE. Still not better.

I tried to remove the GPS enabling (LOCATION_CONTINUOUS) from the application start, and just keeping the LOCATION_DISABLE, but that didn't work neither.

-------------

Besides, I would assume, if GPS is disabled, Edge would collect the distance and speed information from my bike trainer (paired with ANT+ FE-C protocol). But that doesn't work neither. It's not working on 530/830/1030 neither. I can see the correct data, if I check the Edge's default datafields (not in-app).
