A514 55 Shapes of contacts on USB port are different from usual

Chan

The Aspire A514 55 has 2 type A USB ports on the left side 1 type A USB port on the right side,

I note the shape of the copper contacts on right side USB port are different from those on the left side, they have a flat and straight surface instead of the usual curved surface.

What could be the reasons for the difference?

Those USB port shapes are identical only USB3 and C are different (smaller and rounded). maybe you are confusing HDMI or a mini display port for USB? If they look different someone may have forced a USB plug the wrong way and busted the housing.
