Sounds like an OSM tagging issue. If you want to correct them, you can go to openstreetmap.org find the area on the map, and then tap the Edit button. This link explains the tagging convention for path in detail, but in brief its:
highway=footpath for a dedicated foot path (bicycle=yes may be added if bicycle is permitted on it)
highway=cyclepath for a dedicated cycle path
In case it wasn’t clear:
• Foot paths are shown in PE as a red dotted line (short dots).
• Cycle paths are shown as a blue dotted line (short dots).
• Fine black dotted lines (long dashes) and dark orange dotted lines (long dots or alternating long and short dots) are various kinds of trails, mainly for hiking.
• Purple dotted lines are regional/local admin boundaries. These can be turned off in Settings > Map Layers > Subnational Admin Boundaries in case you find these confusing.
