Perhaps the ILS transmitter is not on centerline? They can be offset, but I
don't know by how much.

Three degrees I think. And remember the localizer is at the far end of the
runway (on the front course).

The glide slope transmitter is often separate.

It's always separate. The glide slope transmitter is down approximately
where the touchdown is (and obviously off to the side of the runway).
