Train Simulator: GP40-2 Loco Pack Add-On: Cannot Couple

Hi Guys, This is a weird one. I need a 4 axel Norfolk Southern Unit as a road switcher. I have had the Train Simulator: GP40-2 Loco Pack Add-On since release as it also has an Autoparts Car, and CSX 50 footer.
On to my issues:
1. Coupling to rolling stock causes derailment of the target car (RSC UP, RSC Undecorated 60" and Sherman Hill 60' Boxcars)
2. Coupling to rolling stock does not occur (RSC UP, RSC Undecorated 60" and Sherman Hill 60' Boxcars)
3. Coupling to another GP40-2 does not occur.
3. It will couple to an NJT Comet III coach
4. Same issue with the GP38-2NSPack01.
Steps:
1. Testing same coupling with NS Big 7 Pack and the NS SW1500 ( no issues)
2. Deleted C$\Program Files (x86)\Steam\steamapps\common\railworks\Assets\DTG\GP40-2Pack01 and performed File Validation
3. Reboot Machine.
4. Testing only done on the Bergen (oh-oh!)
Note Full Reverse being applied and no other unit attached in the couple view.
Does anyone have any idea as to why this is occurring and if so, how to resolve.
