Haven't had this issue with a spectral CF 2018; I have always used plastic spacers (slammed), but after I replaced the stock stem with one with lower stack, I needed another small spacer.
I have noted that the recommended torque max is 1.5-2 Nm for the stem cap, but I don't recall if I had to over tighten it.
What year is yours? (I don't know if the headsets have changed)
