I worked on this problem for several hours and then shortly after posting here I found the problem.
It would appear that if you use the name of a vlan as the name of the acl then it creates this problem.
This might be a bug but also might be by design. Someone should look into this.
Thank you for asking this question in the support community. When you get a chance, will you provide some additional information and examples about what you were doing that was causing the issue? This will allow me to try to determine what the problem was.
