So there is no problem.

dpkg -p is shows the available packages for dselect. Since apt and dselect uses
different mechanisms for tracking package status, dselect's availability
database (/var/lib/dpkg/available) is not getting updated, hence reflects
initial installation status.

You can update this database with "dpkg --update-avail" but since you won't be
using dselect anyway, it is futile to do so.

So I would suggest use "dpkg -s" for actual installed package status, and
forget about dselect's idea of available packages (dpkg -p).

More information can be found in dpkg(1) man page.
