Yea templates get even more interesting. See Ghost Template.

The save DC against a ghost's special attack is equal to 10 + 1/2 ghost's HD + ghost's Charisma modifier unless otherwise noted. Additional ghost abilities beyond these can be designed at the GM's discretion.

If I follow everything correctly when a template says "Ghost HD" that includes both Racial and Non-Racial Hit Dice. So in that case it should include both.

Yep here is a fix note from HL release notes that says "Ghost abilities from Classic Horrors Revisited were calculating their DCs from racial Hit Dice not total Hit Dice."

So a standard Racial Special should NOT calc from non-racial Hit Dice. But Ghost template abilities should.

If you want a Racial Special to calculate its DC based on ALL Hit Dice (Racial and non-Racial) the fix is to add a "Tag" using the Blue Button "Tags". Left mouse press "Click to add another tag".

Then enter the following:
Group ID: Helper
Tag ID: DCUseTotHD

P.S. - My bad mentioning the adjustment at first as I didn't catch you where making a new Undead creature in the editor.
