Waypoints not exporting?

I have a collection of points with pictures attached that I can't seem to export. On my phone, I export the points as a kmz/kml file to internal memory, the file is over a Gigabyte large and ends up as a kmz. However, when I transfer it to my computer or try to import it to google earth, I get a pop-up stating that the kml file is empty. On the one occasion where it showed up in the export folder as a kml instead of a kmz, I get an error stating that there was a parsing error with an unclosed CDATA section. The points do not show up on my map when imported. I am new to Locus Map Pro, so I may be doing something wrong. Am I doing something wrong during the exporting process, or is this a bug?
