Sample utterances used for model building don't work well

I have sample utterances like this -

How to make {NameOfTheDish}
How to make the dish {NameOfTheDish}

Now, if I say "how to make thiramisu", I get "thiramisu" as the slot value.

But when I say "how to make the dish thiramisu", I get "the dish thiramisu" as the slot value.

Looks like ASK is just matching greedily instead of checking for longer / better matches in the model.

The surprising part is that even when I change the model to just include one sample utterance -

How to make the dish {NameOfTheDish}

the utterance "how to make the dish thiramisu", still returns "the dish thiramisu" as the slot value.

Expected:

"thiramisu" should be the slot value in both utterances.
