TextMesh Pro Buttons and sliders don't read to input.

Hello.
I've made a basic UI system for my game that was working. I've made more content for the game and the UI buttons and sliders no longer react. I've searched many unity forum threads and found no solution. I tried a canvas group, checked if the elements have graphic raycasters and I checeked if every element has the Raycast Target checked. Its the secound time this has happened to me and the only "solution" I've found so far is to make the UI once again.
