Isn't that supposed to happen
The title seem to be a statement, the body a question about something "happening" ...
Perhaps you could unpack a little ?
( Topic and question still a bit unclear )
Hello @GregT
To me it seems you’re talking about the two integrated Smart Groups.
If that’s the case, then you maybe should export all your Macros, despite the built in ones that come with every installation of KM.
After exporting them you should quit KM and KM Engine altogether and remove everything related to KM from your Mac, restart it and install a fresh downloaded copy of KM.
After that Try to disable some of the built in Macros and make sure that those are listed in the Disabled Macros Smart Group.
If that’s like it is supposed to be - then you’re all good and can import your own Macros into KM.
If not you’ll maybe need help form Peter (@peternlewis).
Be aware that - if your Macros contain Custom PlugIns - you’ll have to save and restore them, too.
