Hi Jeff,

Your code looks fine and this is the correct way to retrieve custom attribute's value. I have created a small samples based on the provided information. However I was not able to reproduce the same behavior as you. For your reference I'm attaching my sample. Please check it out and let me know if I have missed something.

Thanks.
