Hello,
Not sure if this is a bug or something I missed. I tried to add a path parameter for an operation as shown below. The "Add" was greyed out and thus I was not able to save the path parameter.
Could anyone please give some tip?

BTW, there was no such an issue in API Connect 10.0.5.4 release. I just checked release 10.0.5.5, which has the same issue. It looks like the issue was introduced in 10.0.5.5 unless I missed anything.
Thanks and happy holidays!
