[Closed] Sender ramp: is this normal?

Just watched the assembly video for the curved 350 (slightly disappointed at the lack of pre-drilled pilot holes, but hey ho) and the transverse part at the top of the rear doesn’t have an angled top edge as shown on the video (NB I have the Pro version whereas the video shows the standard one, but I can’t see them differing in this respect). This means it protrudes at least 2mm either above (see photo) or below the sides, which will either stop the ramp surface fitting flush or will prevent the sides folding.

So: sanity checking, am I right in thinking that I need to request a replacement part (I don’t have the tools to cut the angle myself), or is this normal and I should just crack on?
