Log Downloader shifted enumeration of logs

As can be seen in the screenshot, logged flights are enumerated starting from 1 in the left pane but seem to be enumerated starting at 0 internally as can be seen in the right pane where the error occurs for log 6 / 5.
Suggestion: adapt the left pane to also enumerate starting at 0.


Start with the Mission Planner Log Downloader and reproduce the log 6 / 5 error shown in the issue screenshot. Inspect how the left pane labels logged flights versus the internal selection, and consider the issue complete when the displayed numbering matches the numbering used during download.
