Declined 'Unable to verify' but all the information is from IMDb

My contribution 221213-220112-783000 was declined ‘Unable to verify’. The explanation I included was:

She is credited as Will Mellor's wife and was named on screen only as 'Michelle'. His biography https://www.imdb.com/name/nm0578123/bio says that Will Mellor's wife is Michelle McSween who has a page at https://www.imdb.com/name/nm1945661/

This was a merge of Michelle(CCXX) to Michelle McSween.

If you go to the page for Michelle(CCXX)  you can see she has only one credit: "Self - Will's wife" on Strictly Come Dancing Season 20  Episode 23 - and also on that episode is Will Mellor  "Self - Contestant".

If you look at Will Mellor's biography using the link that I included in the explanation you will see "He has been married to Michelle McSween since August 2007." and also an entry as "Spouse" in the family section.

What more information should I have added to the explanation to make it possible to verify the contribution? As far as I can see, all the information that is needed is from IMDb and is at most one or two clicks away.

On a related point, the bio page says "They have one child." and the Spouse entry says (1 child). There are now links to their two children who appeared named on screen supporting Will both in the main series of Strictly Come Dancing and its companion show. The two child links were added in my contribution 221213-220549-021000 and were accepted. The correction to the Spouse entry to say '2 children' rather than '1 child' was in the same contribution but was declined. This leaves the bio page with an obvious inconsistency.
