PT 11 "stock" IO Settings CAN'T be deleted?

Now that PT's IO Settings are stored in user/Documents/Pro Tools it seems that EACH TIME you launch PT, it automatically populates this folder with:

C24 LE stereo

C24 Mix

Control 24 Mix

Control24 LE Stereo

Eleven Rack

ICON X-Mon Mix



I use a number of "custom" IO setups across a number of systems, and am finding these to be "getting in the way" when quickly trying to import / re-import settings.



Any ideas why legacy controllers that are NO LONGER Compatible with PT 11 would load as a choice for IO Settings?
