Clarification needed

Maybe Bug, Maybe User error. Would very much appreciate some clarity on the subject. 

I was advised that the term "CNC Precision milled" violated terms and conditions. I'm an engineer and was looking for some starting points on a logo redesign and I am Highly Likely to use all of these terms again.

Can you please advise me as to what, specifically is in violation because I'd prefer to not lose access to my adobe services,
