Query Stern JP2, helipad screws

[zxspectrum16k]

I'm hoping someone with a Jurassic Park could check theirs for me.
I noticed on mine the two screws just on the helipad lane (lower right) are quite big and protrude a lot on the playfield. I think these will impact the ball travel. I'm wondering if these are supposed to have a flat head instead.
I noticed a strong plunger shot sometimes fails to make the shot up and I wondered if it had anything to do with that.

Just roll the ball along the guide and over the screw head, pretty sure it won’t contact it.
