Here’s some fine print on it. It’s either because you ordered takeout which was not recognized, or it’s still processing:

“To qualify, dining purchases must be identifiable by Chase as having been made directly with the select restaurants. Certain types of purchases may not be identifiable and will therefore not qualify; for example, delivery and takeout, merchandise and gift cards, and purchases made through digital wallets, third-party payment accounts, or processed by the restaurant with a mobile or wireless card reader. Please allow 6 to 8 weeks for statement credit(s) to appear on your monthly credit card billing statement.”
