Duo Push 2 notifications

I have a Watchguard SSL VPN running and have setup Duo to authenticate using the AD client. When I try and connect I get 2 prompts. Both have to be approved. I have set them up like another client of mine but they receive 2 prompts and I can’t seem to find out why. Both companies are running the same Firewall version and client. I am using the same machine to test both. Active Directory is the same version as well. I have read through others having this issue and it does always point to the system authenticating against. I just can’t see any difference in the 2. But there might be something I am missing. At a loss
