Princes of the Apocalypse Map Bug

I just bought the Princes of the Apocalypse module and was on the Red Larch Surroundings map.  My player's characters are from the area (we are starting at level 1) so I was going on the map and changing the paths from the GM layer to the map layer as I believe my characters would know the Cairn Road and the Larch Path.  When I moved the Larch path (red dotted path) to the map layer, it disappeared entirely and would not be undone.  Okay, probably my error so I restarted a new game with the module and went to change the Larch Path from GM layer to map layer and once again, it disappeared entirely.  I restarted a third time and same result.  The other paths were able to be transitioned to the map layer with no issues.  This must be a bug and not my user error.  Is there some way I can get the map with the Larch Path (red dots) to be visible by my players?  Does anyone have a solution for this?  Will the red dot trail just never be visible to my players?

If you right click a token/image, there is an option to move it to the back or to the front.  It might be that your path is set "to the back" meaning that when you drop it from the GM layer to the map layer, it is automatically going behind your map.  You might try selecting your map, right click, select "to the back", and see if that makes your path visible.

That is what had happened.  For some reason, there are two maps on top of each other and it went on the map beneath the top map.  I moved the top map to the bottom and got my trail back.  Thanks so much Kraynic!

There is only one map... the path was in the back, now the map is in the back.
