A few things to check:

1) Examine the exterior door casing top and sides. Ensure they are
caulked with an exterior acrylic caulk.

2) Pull the metal threshold for inspection. The threshold should also
be caulked underneath - width of the threshold along the door jamb and
a two beads the width of the door. (~1/2" size beads)

Looks like: (sorta)

3) Inspect the interior top trim casing - looks like there could
possibly be water intrusion at the height, can't really tell. If so,
is it may be possible the door install was not flashed properly with
"moist wrap".

This needs a very close inspection all around. The water will
eventually cause harm to your wood flooring. Allow wind drafts and
blowing rain to get inside.

Are you handy? Maybe pull the interior door trim casing too and have a
look behind it.

Let us know what you find, please.
