Hi,
Are you saying that when you click All Products tab that ALL of the different VMs (even if you page through all pages) for US West 2 are showing the information icon on the left? Or is it just for the VM instances you currently have deployed in US West 2?
I recommend you open a support request asking for the vm family types you are interested in for US West 2 and see what response you get back. And if you are blocked from purchasing any VM reservations in US West 2 you can ask them why while you are discussing things. There is no charge even if you don't have paid support because it is a service and subscription limits case.
Article below explains the process. Read down some for where it specifically mentions reserved instances:

Thanks.
