Opening issue here as requested on Discord.

What is the version of xEdit you are using?
TES5Edit 4.0.2k (63956442) starting session 2019-11-08 22:59:27

Describe the bug
There is an ambiguity in the QUST definition for Skyrim. QSTA subrecords can belong to either the Objectives\Targets section or the Targets section, and if there are no subrecords between the two, it becomes impossible to add any to the Targets section.

To reproduce

1. Make a new, completely blank QUST in xEdit
2. Add an Objectives section
3. Add a Targets section (at the very bottom, not in the objectives section)
4. Save and relaunch - notice that the targets have now moved up into the objectives section

Expected behavior
Saving the plugin in the CK readds the DNAM, NEXT and ANAM subrecords, which obviously solves the problem - maybe ANAM should be required?
