Broken valve shim

Yesterday while starting with the regular maintenance for the coming season, here was what I discovered while removing the camshafts to see why the valve specs were that out of range.

To be noted, that is 2015 CUP bike and has some 25 hours at the engine spent most of the time at WOT, but still a shim to be split in half, that I have not heard before.
