Dialogflow CX Issue with no-match when parameter is defined on a page

[hockea]

Hi,

I am pretty new to Dialogflow CX.
I wonder whether you can help me to understand an issue I am seeing with no-match event handlers when creating a parameter on a page.

I have a page where I have a fulfillment (question) and a parameter to capture the user input.
The a couple of intent routes and if nothing matches then there are two event-handlers (sys-no-match-1 and sys-no-match-2):

I have figured out during testing that I have to put ina a wrong keyword (i.e. word that doesn't match) twice in order to trigger sys.no-match-1:

What is wrong in this configuration ?

If I don't create that parameter on this page, the logic will work but I have to capture the last utterance of the user as I have to call a webhook later in the flow with this information.
