FACT RNAV (RNP) Z 19 approach constraints incorrect

Flying the A320NEO, on approach to FACT via the RNAV (RNP) Z Rwy 19, the altitude constraints for the waypoints CT414 and CT412 are shown on the ND as 7500ft. This causes air traffic to the issue a descend to 3000ft at CT3000 instruction too late leaving the aircraft too high.

According to the real world approach chart the 7500ft constraint only applies at waypoint CT416 allowing the aircraft a gradual descent to 3000ft at CT410.
