I’ve upgraded the feed to our kitchen electric range from 3 wire to 3 wire and ground. Should I also upgrade the 50 amp 240 vac breaker at the same time to a 240vac GFCI circuit breaker? The instruction booklet with the GFCI breaker says that an electric range with the case grounded to the ground connection should not be connected to the load of the GFCI breaker.
Can anyone tell me why this is the case?

Because it will trip the breaker.
But you don't need a GFCI breaker there (unless some local code guys have gone overboard). Remove the jumper between the neutral and ground in the range (which by now should have a 4-wire "pigtail") and the unit will be quite safe without need for a GFCI. (Plus, if you really want the GFCI, it will then work with the GFCI.)
