error designing one or more section cuts

Question

I have user defined story seismic forces which are causing the error "error designing one or more section cuts". I've went through the suggested fixes for this error but that didn't help. I then discovered that I only get this error when I'm running the user defined story forces load cases. If I'm running the ASCE seismic load cases, the shear wall design module goes smoothly with no errors. Any suggestions as to why this is happening only when running the user defined cases? Thanks!

It also works for me in version 17.02.01.23. In that test I analyzed just the two gravity cases and 2 of the seismic cases (consistent with the way you had it). Then in concrete shear wall I generated valid load combinations and checked a few walls. 
 It's worth noting that you don't have to use custom combinations if the load factors are all the same as you get with generated load combinations. 
 I would also recommend splitting WDG#2 into two separate design groups since the two walls do not touch.

It's working fine for me in verison 17.03.00.282 (a pre-release test build). I tested a few walls (most with hinge sections) and with all lateral load cases analyzed. 
 
 That would indicate some sort of issue that we already fixed. I'll try to reproduce the issue in the release build.
