The slightly more promising answer here is that while there definitely were some serious issues on that page in 9.2, they've all been resolved as part of the admin console rewrite in 9.5, so upgrading should straighten you out.
If upgrading isn't in the cards right now, if I remember right the problems on thate page in those older versions were largely around multi-store functionality and StoreIDs not being set/looked up properly. You might try setting the AllowShippingFiltering GlobalConfig to true temporarily, and see if you get the options you're looking for. It'd be best to try that in a staging/dev environment first of course.
