ZL Button Spring not working

I am trying to reassemble the left Joycon 2, and when I want to attach the ZL button, it feels like the spring is not doing its work. The ZL button is really steady and almost rubbing the button, so with a little touch it will press it.

Hello,

I was changing the covers. At the end I found the issue. The flex was not seating well on the support. From the top it looked like it was in the support, but I saw it sideways and it was not. This is why the ZL button was almost touching the button.

Thank you for reaching out!
