Setlist file format

I have looked around, but haven’t seen anything so far. Currently, I am helping a band with their playback situation, part of which is switching them to Ableset! When exporting setlists from the Setlist (ver 3.6), I have been unable to import them into Ableset. So far I have tried .json and .txt files. Where am I going wrong? What one little simple thing am I missing while exporting or importing?

Could you email me your project file and some exported setlists to so I can inspect what might be going wrong? Just the .als file and the .txt/.json exports should suffice for this.
