GPX Viewer

​In GPX Viewer Pro v1.52.1 (build 516) running on a OnePlus Nord 4 with OxygenOS 16.0.5, the app fails to display individual track segments (daily tracks) in isolation when navigating forward or backward through a multi-track GPX file.

​This issue occurs across all multi-track GPX files regardless of their source or creation tool.

While the app correctly centers the map on the selected day/track, it fails to hide or filter out the other daily tracks.

As a result, all daily tracks remain visible simultaneously on the map, which is a regression from previous versions where selecting a specific day successfully isolated that single track view.

​Environment Details

• ​Device: OnePlus Nord 4
• ​App Name: GPX Viewer Pro
• ​App Version: v1.52.1 (build 516)
• ​Operating System: OxygenOS 16.0.5 (Android)
• ​Issue Type: Functional Regression / Display Bug
• Scope: Affects all multi-track GPX files

​Steps to Reproduce

• Open GPX Viewer Pro v1.52.1 (build 516) on a OnePlus
• Nord 4 running OxygenOS 16.0.5.
• ​Load any multi-track GPX file containing multiple daily tracks or segments.
• ​Use the forward or backward navigation controls to switch between individual day tracks.

​Observed Behavior: The map correctly centers on the newly selected day's track, but all other daily tracks remain visible on the screen.

​Expected Behavior: Only the currently selected day's track should remain visible, while tracks from other days should be hidden (as behaved in previous versions).
