You have a remarkable determination to skip the basics….and I’m stubborn enough to continue recommending: PLEASE review the "Load Cases" document, is a good guide on the subject.
Probably one point you are missing is the fact Spring Hanger is physically a (special) support but is rather a force for the calculation. Now it makes sense for you to have H in both OPE and SUS, but not in HGR (where H is resolved)?
So please review the basics, otherwise you’ll have for ever such doubts!

Best regards,
