The export files option on the latest commit snapshot "fixes to creation of filename/path from format" is no functioning correctly. The first variable in the folder format is creating a folder with the variable itself as a name.

Reverting back to previous snapshot from last Friday "fix: the "all" row in FPanes should not have children" solves the problem.

Example: Album Artist is "PJ Harvey", Album is "Dry", Media Player is "ipod". Folder format is ipod/%A/Dry.
This is also the case with other fields. Filenames themselves are behaving correctly.

Let me know if you need any more information.
