In a professional and courteous manner, discuss this with the service manager and/or the general manager, calmly explaining the situation. Meet them half way by admitting that to err is human (their error, which you can forgive with a replacement part), but that you feel the warning label should have been left on the Givi for you to see, understand, and then remove yourself. I don't think you had any obligation to open the package to inspect your old shield to discover the other shield's stickers and labels.
Tell them you chose their shop over the others out there and that you'd certainly like to maintain a good two-way street of business in the future, and that a way for that to happen is to have them replace the damaged part. The wholesale cost of that part is not going to tip their balance sheet at the end of the month, and it will demonstrate to you that they are a stand-up operation. (If I were in their shoes, it wouldn't take me two seconds to make it right with you.)
If they tell you to go blow smoke, then they will have demonstrated to you their true colors and they will pay dearly for that in the future with lost business from you, and likely everyone you tell your story to.
