The Android interface uses the v3 infrastructure. Not sure why v2 is giving the wrong rating ranges but since v3 is working towards release, I'm not sure anything will be fixed on it.
I haven't been a basic member for a while and wasn't aware of #2.
You might switch over to v3 instead. Not sure if #2 is there but the tactics choices should be in your rating range.
I've experienced the following 2 changes with tactics trainer recently - was wondering if others have?
1) When I now play TT via the v2 interface, it gives me problems rated in the 1100s. I am rated 1750 or so - this is very odd. If I play via the Android interface, I get problems suitable for my rating.
2) As of 2/13, I no longer get an option to watch a video to unlock 5 more puzzles. (I'm a cheapskate free member at the moment). This option was available once every 24 hours.
