   APM 10.7 users, after upgrading from any previous release are unable to edit some universes. (Those that contain business transaction coverage and follow a transaction path) This is due to invisible universe filter editor.
Note that fresh APM10.7 installations are not affected.
  APM 10.7.0 
  The universe filter was not viewable due to a missing layer property.
  This is fixed as part of 10.7 HF1

This includes “DE352438 - Added the upgrade of universes from 10.5 format to 10.7 (added missing layer property)" which fixes the visibility of the universe filter and converts them to the new APM10.7 format.
