GPS Log 2.5 added the ability to re-order and hide the various sections of a log entry.
However, there is a critical bug with this feature. The App will likely crash when you edit an entry if certain rows are hidden.
Until the 2.5.2 update is LIVE, please do not use the Customization feature to hide any of the sections.
If you have already, then ensure that in GPS Log -> Settings -> Customization - Re-order Log Sections, none of the sections are below the row titled "--- [rows below are hidden] ---"
If you are having any issues, please go to GPS Log -> Settings -> Customization - Re-order Log Sections, and tap the "Reset to Default" button.
Sorry for this issue.
Very special thanks to @initialLED for spotting this bug, and helping diagnose the issue.
Regards,
Will
