Should I be worried?
I believe you're fine with the sticker amendment. I have numerous amendments in one of my US passports that sometimes have a seal, and sometimes not. The last time I had a double insert was about three months ago, and they did carry the raised seal under the stamped phrase (not a sticker) that is essentially identical to the phrase on your sticker. US embassies and consulates have some flex in their procedures.
Happy travels
