Apologies for not following this thread.  But offhand I'd say that
there's your problem right there: you enable `delete-selection-mode'
but you disable `transient-mark-mode'.  That should be a no-no.

See `C-h f delete-selection-mode':

 When Delete Selection mode is enabled, Transient Mark mode is also
 enabled, typed text replaces the selection if the selection is active,
 and DEL deletes the selection.  Otherwise, typed text is just inserted
 at point, as usual.

d-s-mode ENABLES t-m-mode, on purpose.
