Adobe Acrobat DC Missing from Contracts

Why is Adobe Acrobat Pro DC Missing from Contracts as a product selection? Adobe Acrobat Reader DC is available, but not Acrobat Pro DC. There is a catalog entry for Acrobat Pro DC, so why doesn’t it appear in Contracts.

Additionally, when I attempt to add Adobe Acrobat Pro DC, I get a message that the product already exists.

I see Adobe Acrobat Pro DC under Software Releases and signatures, but not under Software Versions or Software Products when I look in the catalog.
