How FTM considers media to be unlinked. Media can be linked to a person, an individual's fact eg birth and a shared fact eg Marriage. There appears to be a bug when media is only linked to a shared fact and FTM still regards this as unlinked.The question was pages long and will not publish this long question.
As a user, I have no way of dealing with "bugs" in Family Tree Maker. Those questions need to go directly to http://www.familytreemaker.com. feed back link.
Secondly, I don't understand the question, Unlinked Media to a Shared Fact.
Thirdly, a Media file can be linked to one of two places: to a Person or a Citation
So, there is not a way to directly link a media file to a Fact, shared or an individual fact.
Now, if the Media file is linked to a Citation, and the Citation is linked to a Shared Fact, that Media FILE would be linked to that Shared Fact.
I do not consider the question to be reporting a "bug" FTM2017 works as expected as seen above. That Media file is the record of that marriage.
