Prevailing Wage Offset and 401(a)(4)

Hi, 

I am working on a profit sharing projection for a safe harbor match plan with prevailing wage (ugh).  The eligibility for sources other than PW is 21/1 YOS/semi-annual.  There are 4 employees receiving PW - one is HCE (another ugh) and one never met YOS.  I was able to disaggregate those not meeting the YOS so the OEE that has PW doesn't need to receive the gateway.  

The employer gave specific $ amount for several participants and I backed into the HCE $$ by giving them 3x so it passes gateway.  Not all NHCEs (6 don't) receive a PS - it's SH Match and this passes.  

My question is related to the those in the main test - if the document states that PW offset PS, SHM and Match - I am struggling to get ASC to run how I think it should be run.  If I click on PW to include in gateway, then it uses PW eligibility and includes ALL employees and is saying it fails gateway because those 6 participants are not receiving a PS. My understanding (and I could very well be wrong), I thought PW would offset PS and would be counted in ABPT but NOT in ABT.  The lowest NHCE was 2.65%, so I gave HCES 7.95%.  However, the HCE that has PW only shows .21% on the gateway test because most of his ER is coming from PW - the rest is PW.  

I messaged ASC to see if there is a work around but figured I'd check with you gurus as well.
