Try going into a completely blank model and see if these EPA adjustments change your subtrim. Normally you should set the End Points first before setting any Subtrim. And subtrim is only meant to be used in very small amounts.
If the subtrim is still affected in a new blank model, we would recommend sending this in to be checked out.
