Autofocus issues

Hey all,
I've been running into a weird issue after switching to the QHYMinicam8 with the integrated filter wheel. 
I was previously using the ZWO ASI 1600MM Pro with 1.25" filters in a ZWO filter wheel, but since switching to the QHY I seem to have issues any time autofocus happens when the SII filter is active. 
It doesn't appear to be affecting Ha or OIII, just the SII channel. 

In the ASI Air I used previously I had autofocus set to trigger after filter change and now since I switched to N.I.N.A I decided to use the Autofocus on HFR change instead since the filters should be theoretically parfocal. 

Any insight you have is appreciated, thank you.
