The axis indicator is not displayed in the 3D window even though it is checked in the 3D Ribbon Fast settings
The "View Cube Manipulator" check box in the 3D ribbon>Fast Settings is to toggle between XYZ arrow axis indicator and View Cube.
Try the following:
1) Ensure that the Axis Indiator is turned on at all: toggle on the Axis Indicator in 3D ribbon>Indicators drop-down
2) Try going to Options>3D View>Advanced and switch to the Direct X11 driver
3) Try pressing F5 on the keyboard to refresh the display, or closing and re-opening Synchro
