The firing pin is probably too heavy for non-military primer - this is a recurring problem for military rifle adapted to civilian configuration. FN2000 had the same initial issue until they were retrofit with a spring.
They need to reduce the mass of the firing pin ( but this is a risky route because there is no long term testing for the durability of the firing pin), or they have to put a spring in the firing pin chanal.
However, since mil-spec 5.56 ammo is ini short supply, it is impractical or if not impossible to feed only military ammo.
