B-747-8 2500 FT Altitude Callout Unreliable after SU 11

After installing SU 11, has anyone noticed that while using the B-747-8, the 2500FT altitude callout is no longer accurate. Crossing the altitude 10 times, you’ll maybe get the first one correctly, but after that, every single callout will be totally inaccurate (sometimes by over 1500FT). I have no addons on my system and my install is totally default. I’m running Windows 10 and my computer is a fast new one.
Thanks.

It appears that after SU12, the 2500ft GPWS Callout on the B-747-8 still has not been fixed. This problem started after SU11. Basically, the callout is way off-1000-1400ft off. Was hoping that it would have been corrected with SU12, but no.
