I called the folks at Wiz & they say it should be HOEPA
Whoa.
Your index may not be the same for HOEPA as it is for HMDA. It is possible your spread for HMDA could be 8.13 but your spread for HOEPA would be below the 8% threshold for a first lien loan.
HMDA uses the constant treasury index as of the 15th of the month prior to the final rate being set. HOEPA uses the constant treasury index as of the 15th of the month preceding the month in which the application was received. Therefore you are most likely comparing your spread to two separate index figures.
Double check your HOEPA calculation. I don't use CRA Wiz but based on your post I'm not convinced that you "absolutely" have a HOEPA loan because your HMDA spread in 8.13. You have to make sure the proper index is being used for each calculation.
