My Dad's Ordinances don't show he was BIC
@NidaLewis to get an answer to this, you should put the PID of your father and then people looking at this will have a place to start looking.
There are two possibilities for this.
1) There is a duplicate for your father in Family Tree that has not been merged in yet. It may take some creative searching to find it.
2) The most common reason for this is due to the fact that BIC is not an ordinance. In the initial import of information into Family Tree, since the membership records for people designated BIC did not have a date, that field in Family Tree was also left blank. I sent in a several dozen requests to FamilySearch support to ask to have BIC added to relatives. They were always very quick to fix this. Just go to Contact Us under the help menu (the ? icon in the top right corner), explain the situation, include his ID number, and they can just check his birth date against his parents' sealing date and add BIC. They are the only ones that can fix this.
Further to what 'Gordon' has proffered ...
Plus, the fact that there are two (x2) 'Databases' involved, being, 'FamilySearch' "Family Tree" database; and, the "Temple" database; where, "Interface" problems/issue can arise; especially, with "Merging"/"Combining" ...
Here is a "Knowledge Article" in 'FamilySearch':
IF, after following the "Steps" (ie. Making sure the CORRECT "Parent-Child" Relationships exists; and, checking for any "Duplicates") in that "Knowledge Article" still DOES NOT resolve the situation; THEN, as suggested, BOTH, in that "Knowledge Article"; and, as, 'Gordon' has inferred ...
Submit a 'FamilySearch' "Support" Case, with any Evidence/Proof at hand (ie. available to you), requesting the "Ordinance" of "Sealing to Parents" ( SP ) for you Father be "Changed"/"Corrected" to "𝑩𝑰𝑪".
I hope this helps.
