So, recently I've only been using pocket queries to load caches on to my GPS.

But the .zip file I download and subsequently copy and paste in to the GPX folder of my GPS isn't showing the caches when I go on the GPS itself. This sounds odd, right?

So I copy the .zip file in.
Turn on the GPS to check the caches are there, and they are not. As if I'd never pasted the file.

However, after a while of pasting it in a lot more times, a folder (with GPX files, which are needed of course) shows up, and then the caches appear on the GPS 

Anyone have any clue what's going on, and why the GPX files take so long to appear 

The .zip file needs to be un-zipped, and then the ,gpx and wpts .gpx file copied to the GPS.
