Console React error

Hello, when following the tutorial and on step 3 it looks like the image is causing an error with React and is not displaying. It’s only from the WP backend, not the front end preview:

WP: v6.2
Pinegrow Plugin: v1.0.9

react.js?ver=18.2.0:199 Warning: Each child in a list should have a unique "key" prop.

Check the top-level render call using <div>. See https://reactjs.org/link/warning-keys for more information.

@billiemead this is just a warning, it should not impact the function of the block.
