File>Export>Export Macros.. bug?

If I

  • select a macro → File>Export>Export Macros.. → a backup copy is created
  • open keyboard maestro→ select macro group → File>Export>Export Macros.. → a backup copy of all macros in the group in created

If I first click on a macro, then decide that I want to export the whole group it belongs to → click on (select) that macro's macro group → File>Export>Export Macros.. → keyboard maestro backs up the previously (and currently greyed out) macro instead of backing up the macro group.

thank you
