Why is reward availability often worse when logged in as a plat elite vs not logged in at all?

I'm trying to find standard BF rewards from IAH-BRS this July and I see more availability and options when logged out than I do when I'm logged in. Additionally the same thing seemed to happen when I called reservations.

Surely the whole idea behind more reward availability for plat elites is that the standard reward buckets are a subset of the plat reward buckets, not the other way around. Shouldn't availability in 'EN' always be >= availability in 'E' ?

Thanks
