This loops looks counterclockwise when viewed from above, so currents flowing Up appear flowing out from the loop and thus count as positive, while currents flowing Down appear flowing into the loop and thus count as negative. Hence, for this loop, Inet is the net current through the loop in the upward direction.

-the enclosed net current is zero

In the image, above the entire field is perpendicular to the Amperian curve when it enters the curve, but is not entirely perpendicular to the closed Amperian curve when it leaves. Therefore the dot product will be greater when the lines enter than when they leave, so the net circulation wouldn't be zero would it?

However, the net current is zero, so the net circulation should be zero right? What am I misunderstanding?

I would like to know what the expression "net current" means.
It's similar to the notion of "net force". If you consider all the forces acting on an object, the net force is simply the vector sum - it's the resultant force.

Similarly, the "vector" sum of currents (in is positive, out is negative) gives the net current into the node.

(If you reverse the sign convention above, you get the net current out of the node.)

KCL simply says that the net current into (or out of) a node is zero.

Kirchhoff’s current law (KCL)
No point in the circuit accumulates charge. This is the basic consideration here. Then, the principle of conservation of charge implies that the amount of current flowing towards a point should be equal to the amount of current flowing away from that point. In other words, net current at a point in the circuit is zero. We follow the convention whereby incoming current is treated as positive and outgoing current as negative.
