Book boxes continuing series they have done special editions for outside of the monthly box

Why is it that fairyloot focus on different special editions instead of finishing series they have already started?

Will they ever do an edition of the 3rd book in the daughter of the pirate king series?

Also (I don’t know if they have continued this) the other books in the Graves Glen series?

I’m starting to regret buying special editions for series they are not prioritising because I was to finish them but I am not paying twice.
