Every piece of armored clothing can be upgraded except for the clean black suit

[ACanOfWin]

I've been buying up all of the armored clothing from Tinker Tom, and wanted the clean black suit. To my surprise, the clean black suit is the only one without the ballistic weave mod installed, so I cannot upgrade it. I tried to add the mod via console command ([suit ID].amod 0020de42), but it told me that the parameter must be object mod type. Is this a bug? Has anyone else tried this?
