If anyone is still dealing with this I've had some luck following the procedure at the following:
https://kb.vmware.com/s/article/89144
I initially had issues after I deleted the first controller that was deployed and tried re-deploying it. Once I manually cleaned up the ALB endpoint from an NSX manager, I was able to successfully re-deploy the Advanced Load Balancer using NSX.
One thing to note here. I also got those error messages when deploying the second and third controllers required for a cluster. I was able to follow the same steps to clean up the ALB endpoint and then was successfully able to deploy the additional controllers. The cluster reports that it is stable and all nodes are reporting up in NSX. However, when I query for the ALB endpoint from NSX manager I don't see any reference to it at all anymore. I don't know what kind of issues this may cause down the road. If anyone has some additional information on whether this is good/bad/irrelevant I would be glad to hear it.
