Hello and thank you for trying out OpenLoopz! I'm glad it's proving helpful for you as an organization tool.
Sorry to hear location contexts aren't working for you. The first thing I would suggest is to do a "Reset". You can find this option from the menu on the Home screen.
If that doesn't solve the problem, please let me know the make and model of your device and your Android version, then I can try to suggest more solutions.
Thank you,
Paul Drummond.
