I can’t really walk this through step by step. I can explain it generally though. There is a naming bug in the library export. If you create a Program preset with the same name as a Layer preset and put them both in a library for export, the library export will change the name of one of them to name_1 due to conflicts with both having the same name. The problem with this is that one is a Program and the other is a Layer. This prevents the possibility of having an “Init” program and Layer name within the library. This seems to be a bug because all Default libraries have duplicate names such as “Init Anima” for program level and for Layer level.
