'Similar Libraries' Counts not Updating

At times the 'Similar Libraries' counts on Profile page are either blank ('No books shared with other users.') or are quite off.

For example:
1. https://www.librarything.com/profile/Coleccionando. This member is at the top of my Recent Similar Libraries and second on my Weighted Similar Libraries but on their profile page their Similar Libraries is 'No books shared with other users.' I thought the issue may be that this member only joined on December 10 and something had not yet updated.
2. https://www.librarything.com/profile/jayaero1. Per the Books page for this member, we share 290 books but their Similar Libraries is 'No books shared with other users.' Since this member joined in 2018, there should be no delayed update issue.
3. https://www.librarything.com/profile/TChesney. Per the Books page for this member, we share 620 books but their Similar Libraries show us matching on 504 works despite having only seven or so duplicates.

Another example: https://www.librarything.com/profile/CHS_YWAM has been a member since November 30. While the Books page for this member shows we share 55 books but their Similar Libraries is 'No books shared with other users.'

Another example: on https://www.librarything.com/profile/GilderLehrman profile page, 'Books You Share' shows 6 but when 'See All 6 Books You Share' is clicked and then I'm taken to Books, the count is 148.

Another example: https://www.librarything.com/profile/Mike_AF has been a member since May 2019. The Books page for this member shows we share 106 books but the Profile Similar Libraries shows 'No books shared with other users.'

>4 surly: https://www.librarything.com/profile/Mike_AF says I share no books, but https://www.librarything.com/catalog/Mike_AF says I share 49. The recommendations seem unlikely too - https://www.librarything.com/profile/DuncanHill/recommendations/whatshouldyoubor... recommends 47 books for me to borrow from him, and none for him to borrow from me.

Similar with https://www.librarything.com/profile/GilderLehrman, we do share books, but not according to the profile, and the recommendation disparity is the other way round.

>5 DuncanHill: Re GilderLehrman, for me we share 6 books per Profile page but the Book page number is 148.

Another example:https://www.librarything.com/profile/paulf.77577 has been a member since November 2021. The Books page for this member shows we share 114 books but the Profile Books You Share is 2. The top Profile Similar Libraries raw count is only 12.
