[Coldbox 6.5.2][Lucee 5.3.8] Flash Scope issue

Flash settings in Coldbox.cfc (see attached config code) are not applied in my app (see attached View). Why is flash set to keep=true, when I dump flash.getFlash() in my view? last_url is also polluted with some un-purged random content that causes a redirect error to last_url when the handler processes validation errors on any of my forms. Notice that the default setting is auto purge = true. Coldbox tracker is also attached.
