What caused this horizontal white line scans from film developed at a local shop?

I'm brand new to film photography and I just took my first rolls to a local shop today. The first half of the roll had these horizontal lines at the top and the second half was fine. Is this a film issue or a development or scan issue?

How to isolate an object or drawing when scanning?
