Export Layer Comps incorrectly referencing previous files for naming.

UPDATE: A couple of releated topic threads with better solutions below:

Droplet using a .jsx action not working properly - every file has the same name!

How to make a script for saving out multiple files with layer comps to JPEGs

This by design, the script is intended to work this way.

I have modified the code to use the active document name as the prefix.

I have not performed exhaustive testing, however – it appears to work as intended...
