In that case I would check it has been built according to the drawings
that picture shows 2 or 3 top plates with no support under them, it could well be the picture angle but from my angle that timber sitting under the top plate is not sitting on top of any studs and is just floating there.
do you have a picture of the studs supporting the timber over that opening.
if the timber that is on its side is knotched into the studs then that is the support, but from the inside aspect it looks like they are just nailed in.
better to be safe than sorry after it’s all been covered up.
