Unable to parse Date from user input

I have created a test “book flight” work flow. When I ask the user which date they would like to fly, the flow does not match to a choice. I enter “1 July” and it doesn’t seem to get parsed.

In the IVR project I do not see a date type. I have created an Alexa project and the slot type is “date”.

I am sure it is just me misunderstanding how to use dates correctly. Any advice on what I am doing wrong?
