Remove git contributors from my team

I am trying to remove 4 of the Git Contributors from my team but it is not giving me the option to do so.

The 4 members were only temporary contracted devs who will no longer be working with my company.

Hey there, @JimmyStax90

Thanks for reaching out! I have escalated this to our Support Engineers who will follow up with you directly via email. Stay tuned to your inbox!

I would also like to do this!
