Fixing Distinct ID Issues for User Funnel Tracking in Analytics

HI, I have a funnel that goes from a not loggedIn user to a loggedIn user. I can see the events coming in. even though some of the events share the same anonymousId, their distinctID is sometimes different. eg something like $device:a48b1db7-1c62-47b6-bc02... vs 92929292 the `92929292 comes from a call to analytics.identify with that param... the $device... are coming in from Segment. This seems to be messing up how subsequent events in a funnel are matches. Any hints on resolving this pls?
