I am running GPredict 2.2.1-ubuntu18.04~ppa3. I set the map centering in Preferences/Modules/Map View to -99 which is close to my location. The map did not change from the view centered on 0 (zero). I shut down the program and restarted it. No change to the map position. I checked ~/.conf/Gpredict/gpredict.cfg and it showed that the map should center at -99. Is there something else I need to do?
