Product Library tab only shows one product class

Discussion created by mtrcn on Jul 30, 2013
Hi Team,

Today, we just came up with an interesting issue that we can't understand the reason.

Product Library tab under Data Frame Properties window does not show other product classes, if I create the MXD by using New Product Class action. Indeed, I can see all list if I create the MXD from the scratch via File menu. 

Does anyone know the reason?
