Adapter VMQ and processor groups in Hyper-V (using Switch Embedded Teaming) not working

I thought I had a pretty good understanding of virtual machine queuing but I am getting unexpected results that I do not quite understand.

I have a system that has two processors in it with each processor having 22 logical cores (hyperthreading is DISABLED). This would give me a total of 44 cores. Now I configured the first 10Gbps NIC to use cores 1 through 22 with a maximum of 16 processors (31 receive queues total since I'm using SET) and I configured the second 10Gbps port to use cores 23 through 44.

However, if you look at the assignments below, it is putting some of them on GROUP 1 core 0 which doesn't make any sense. The process groups are only supposed to be getting used if you have more than 64 cores and I do not. Has anyone seen this before or know what is going on?

Hyper-V 2019 running on DL360 Gen9 with 2021-09 CU running switch embedded teaming.

Now when I go and look at "Get-NetAdapterRss" you can see the second NIC has a MaxProcessor of 1:0 which explains why everything one NIC 2 is getting put on 1:0. But why? With VMQ it shows each NIC has 31 queues and the Get-NetadapterRss shows that there is 128 number of receive queues but I can't increase the MaxProcessors above 16 (16 is the max for some reason even though this is a 44 core server):

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
