I have a custom user profile property that is mapped to 2 different managed properties. For some reason, it is only appearing in 1 one of the managed properties. I can confirm the managed properties are identical except for the different crawled properties to which they are mapped (the managed property that works only maps to this one custom user profile property, while the other managed property also maps to several properties).
I have run a full crawl a few times against the People content source to no avail. Do I need to run a full crawl against all the content sources used by the managed property, even if the missing crawled property is in the People content source? Is there anything else I can do short of rebuilding the UPS?
