google analytics – GTM event in database is selected by debug console but does not fire tags


I work on the maisonfribourg.ch website which was developed using grav.

I am trying to track form submissions using GTM.
In the attached image, you will see a blue button, clicking on it, a popup window will appear: Screen capture showing the .

The developer indicates that the site uses dataLayer.push to include the following in the data layer:
requestFile: open
requestFile: sent

These elements respectively follow the opening and sending of a contact form.
I'll start by describing how I try to follow the OPENING of the form.
I want to follow these two actions using GTM, I created a variable named & # 39; requestFile & # 39; so that GTM knows that this is something that interests me.
The variables and triggers that I have created

I created a trigger, based on a custom event
Finally, I created a tag for that
Here is a picture of the final result
The debug console shows that the custom event is pushed into the data layer

So I think the debug console shows that a data layer element exists, but somehow no tag is triggered, not even that of Universal Analytics.

What am I missing? Did I misconfigure something?

Thanks in advance for your help
