Ruby update stack from Cedar14 to heroku18 - ruby-on-rails

Question

I recently update my ruby heroku app from stack cedar14 to heroku18 and I'm facing issue that I can't identify. I'm beginner in ruby's app and I'm totaly lost.
My home page display filter and I don't succeed to display them since I changed the stack app.
Here the app in production in cedar14
App with filters
Here the app in preproduction in heroku18
App without filters
I don't have any error in logs :
