Help fixing Virtual Road Width in T3ED

[PhilPreston]

Having a problem with the virtual road width flagging
On a project where I'm reducing the road width from 4 lanes to 2, the road shoulder is incorrectly flagged.

Instead of being flagged as Dark Green-Outer width of road, the road shoulders are being flagged as regular driving lanes (Light Green flagging), leading to AI cars driving over them unnecessarily

Have used the "Adjust Virtual Road" function in T3ED but it's not correcting the fault.
See screenshot below where circled in blue the road shoulder is correctly flagged Dark Green (unchanged from original track), but circled in yellow the road shoulder is incorrectly flagged as light green

Can anyone help me correct this?
Track is Hometown 000 for NFS3
