John, I can't see your profile based on your privacy settings. On Bernice's profile, the privacy settings do not allow me to click on the edit tab to see the text that is creating the error.
I'd suggest that you copy and paste the code of the sticker here for your sticker and for hers so we can compare. You might also consider opening her profile for editing so that we can help with an edit. Once it is fixed you can always.raise the privacy level later.
