I'm a new customer and I'm trying to launch a win10 spot instance in US East but I'm unable to select the image I want (NV12_v3) - I get the following issue:

As you can see I've increased the quota to cope with the 12vCPUs required.
I'm not using any resources at all so I can't understand why I am unable to get the VM working. It would be great if you could help me understand what I'm doing wrong so that I can fix it myself in future.
