Local Vector variables in functions do not save the Y and Z values

Local Vector variables in functions do not save the Y and Z values.

Possibly connected: after entering the X value, pressing Tab does not move to the Y value. Tabbing from there works as expected.

Reproduced in 4.7.2 binary and Main (//depot/UE4/Promotable-CL-2473270)

1. Open any project
2. Create a new Actor Blueprint
3. Add a new function
4. Add a local vector variable
5. Change X to 10.0, Y to 10.0, and Z to 10.0
6. Compile and Save
7. Click the Event Graph tab
8. Switch back to the Function
9. Click the local vector variable

Result:
The X value is saved as 10.0, but both the Y and Z variable are 0.0

Blueprint local variables don't save all default value changes
