FMC Takeoff Pg 2 Accel & Thr Reduct - Not Reflecting Defaults

For the PMDG 7378 No Winglets livery, I reset the defaults for ACCEL ALT, REDUCTION ALT, & CUTBACK ALTITUDE to 1000 ft instead of the default value of 1500 ft, which I beleive is more in line with US airline practices. See attached screen shots: After making this change, you can see that the FMC TAKEOFF REF page 2/2 still shows ACCEL HT at 1500 AGL and REDUCTION at 1500 AGL. However, during takeoff, it appears that the aircraft when VNAV is used begins accelerating at 1000 AGL and the thrust is reduced also at 1000 AGL as programed on the default page. Has anyone else tried to reset these defaults and is your behavior on takeoff the same? Thanks, Rich BollWichita KS
