In case anyone else was having the same issue after linking your DNS account to Uniregistry: All my names that were set to BIN_ONLY were going to the make offer page. Which made me think they were forcing brokerage, but that's not the case.
Finally, figured out that the Banner link was listed as
http://domainnamesales.com/domain/{DOMAIN}. Once changed to
https://domainnamesales.com/domain/{DOMAIN} the BIN pages would load.
EDIT--Also, was having an issue with being unable to select PPC when editing a specific portfolio...it just wasn't an option. However, if selecting All Market Domains, PPC will be an option. Kind of frustrating, but that's the workaround.
