I don’t see any problem in the file.
Please try to re-export the content from the uTool by using “force overwrite mode”.
Make sure all of your songs are in the same folder/subfolder
If still not success please send me a screenshot from your uTool export screen:
Plug your USB drive to the computer, go to the uTool export tab, select the content what you want to export select the USB drive in the right window. –> Please send me a screenshot from this screen
