I recently updated to 6.3.1 and most of the atc and AI voices use the original P3d. Am I doing something wrong regarding my settings?

These Flight Simulator installations will be updated:
Lockheed Martin’s Prepar3D® v4
No extra variations, only the original voices will be used.
D:\Program Files\Lockheed Martin\Prepar3D v4

ATC phraseology: ICAO
Airline call sign list: Update
Voice tempo: Increased 60%
