Service quota at 100% utilization despite no instances

Hello, I am currently looking to run some p2.xlarge instances in my account. I completed the service quota request to increase my account limit, however after a spot instance was terminated I have been unable to launch more p2.xlarge instances. I have canceled all spot requests and verified that I do not have instances running in other regions with the global view, and the quota utilization is at 0% in the service quotas menu under All P4, P3 and P2 Spot Instance Requests, with a applied quota value of 4. Not sure what else I should be checking or what could be preventing me from launching more p2.xlarge instances. The error message I get when I try to launch another instance in the same region as the quota limit increase is "Instance launch failed: You have requested more vCPU capacity than your current vCPU limit of 0 allows for the instance bucket that the specified instance type belongs to".
