Is my level missing candies at the bottom left?

You are correct @jayclax516. The new fish mechanic disrupted the original mechanic of this level by replacing the four yellow candies required to feed the frog with a fish. However, fishes you can make by matching four candies in a 2x2 square will help you to clear that frosting.

Still, I suggest you report this level to Player Support.

It's best to contact Support via the game app. Open the game and go to the settings menu (cogwheel icon). There tap the '?' icon, then select New Levels/Level Help. Choose any of the topics there and scroll down until you see 'Contact Us' at the bottom. You will receive an automated email at first. Reply to that email and explain your problem, include a screenshot if possible.
