This change has been around for several releases. My guess is that this is the first time you sent books where you noticed it.

You should look at the tweaks (preferences -> advanced -> tweaks), and in particular the tweaks

# Control title and series sorting in the library view.
# If set to 'library_order', Leading articles such as The and A will be ignored.
# If set to 'strictly_alphabetic', the titles will be sorted without processing
# For example, with library_order, The Client will sort under 'C'. With
# strictly_alphabetic, the book will sort under 'T'.
# This flag affects Calibre's library display. It has no effect on devices. In
# addition, titles for books added before changing the flag will retain their
# order until the title is edited. Double-clicking on a title and hitting return
# without changing anything is sufficient to change the sort.
title_series_sorting = 'library_order'

# Control how title and series names are formatted when saving to disk/sending
# to device. If set to library_order, leading articles such as The and A will
# be put at the end
# If set to 'strictly_alphabetic', the titles will be sorted without processing
# For example, with library_order, "The Client" will become "Client, The". With
# strictly_alphabetic, it would remain "The Client".
save_template_title_series_sorting = 'library_order'

My guess is that you want 'strictly_alphabetic' for both.
