So sorry to hear of your father's passing.
Looks like you have a second profile for your father: McHenry-998
Do you have access to your father's profile McHenry-159 (are you a member of his "Trusted List")? If so, you should merge them together.
If you do not have immediate access, then as Vincent has suggested, you'll need to contact info@wikitree.com directly for assistance.
