If I load a trackfile (.gpx) with multittrack (generated by mapsource, and copied via USB to "Interner Speicheroruxmapstracklogs" ) into oruxmaps all included tracks are shown at the same time. But if I take a bigger zoom-level some of the tracks disappear. If I take a little zoom-level the tracks are shown. Can someone help me. (my Version of Oruxmaps is 6.5.10).
