Aliasing leads to splitting members who "favourite" author?

Sorry about not explaining this very well... not sure what happened how, but this is what I just noticed:

ages and ages ago I "favorited" Seneca, this one:

https://www.librarything.com/author/senecaluciusannaeus

but my "favoriting" is showing up only on this author page:

https://www.librarything.com/author/seneca-1

Shouldn't all the favourites be on one page, or all of them on all the alias pages?

In any case, right now it seems people who have favorited the same author are currently split in one group of 33 and the other of 4 members.
