Inconsistent results with geometry parameter sweep for angles 0 and 360 degrees

I am simulating a capacitor and the induced charges on a nearby capacitor.
I keep both capacitors on the same z level and I do a geometric rotation (parameter sweep) of one plate as a function of azimuthal angle (cylindrical coordinates phi) with respect to the central plate.
The problem I have is if I do a parameter sweep from 0 to 360 degrees or if I do two individual simulations at 0 and 360 degrees the results for C11, C21, C31 are not the same when they should be identical for the two. This makes no sense to me.
These were the values I got
C11
theta Capacitance (F)
0 9.111862547159432E-12
360 9.096381389630305E-12
C21
theta Capacitance (F)
0 -2.3988194878868202E-12
360 -2.4001107003279577E-12
C31
theta Capacitance (F)
0 -1.3790871489206654E-13
360 -1.3723926640514952E-13
I mesh it at Extremely fine - so it is not a mesh issue. Could someone shed some light on it?
I have attached the model file but had to remove the solutions because it was just too large.
