I made a simple error when hand editing a preset, and added extra "<" by mistake:
List view stopped displaying my file, and refresh didn't work either. You can import the file, NTLite saves a copy but still won't list it. So the XML parsing isn't warning you that your file is corrupted. The formatting error is my fault, but NTLite should complain instead of silently ignoring it.
<AutoIsoLabel>Win7 SP2 (ESU Ready)<</AutoIsoLabel>
