Warning/error after selecting directory not containing maps

[Ebe66]

When uploading maps to the device, if you accidentally select a folder not containing map tiles you get a warning/error that no map tiles were found (good). But if you, after that, select a folder that does contain map tiles the warning/error message does not disappear. The subsequent upload however does find the tiles and uploads them just fine.
