How to play all the tracks I have on my USB Chip?
 

We have the Mitsubishi ASX 2016 model and I would like to play music I've transferred to a USB chip. The problem is it only plays the tracks it selects. They seem to be in some sort of order from 01 and up, but a lot are being missed out.

For instance it plays the tenth track first, then plays the 19th track, then the 16th track and so on, missing all the tracks in between.. Can't find a directory for the settings online in English.
