Brian, you listed the cross as "supposed to be "Sharon's Delight X Cotton Mouth"
I assume that is Westbourne Cottonmouth?
The AHS 'standard' is that the pod parent is listed first in the parentage. Some hybridizers do not follow that standard in their own listings and sometimes when they register their introductions reverse the order to follow the AHS expected order. But sometimes they forget or do not bother to make the order pod x pollen parent.
As Richard has indicated that Sharon's Delight does not produce white seeds for him you might try asking the seed seller if it was the pod parent or whether WB Cottonmouth was the pod parent.
