My Garage - Cant Add a Particular Vehicle?

[workingfish]

In the "My Garage" I can add and remove vehicles I own to help when searching for compatible car parts.
Except for my Mitsubishi Triton Ute, it finds the exact vehicle through the drop down suggestions no worries but it just wont save it to "My Garage" like is does with other vehicles. any ideas - I have removed all vehicles and readded them, I have tried different browsers on desktop like Chrome and MS Edge, an also cleared cached and tries the mobile App and Android phone - so its seems to be a backend eBay issue and not me.

Is it just me? Exact car make / model steps for others to try:

1. Mitsubishi
2. Triton
3. 2011
4. ML,MN Ute 2.5 DI-D (KA4T) 
5. RWD Diesel 2.5L 4cyl 100kW 4D56-HP
6. 2477cc 100kW (Diesel)
   
   It will select fine and filter results for that vehicle, but as soon as you navigate away, or change to another vehicle, or go to your "My Garage" its nowhere to be found and I have tried this with only "one car", "two cars", "three cars" in my garage and the results are the same - it just vanished.

Maybe try from a different access point. 
There are usually a few different ways to start to add a vehicle. For example do a vehicle check for fitment in a random listing and you will be asked if you want to add to garage. 
Also try deleting a vehicle in your garage before adding another. 
I remember many members having issues over the years with the garage.
