Loading transition not smooth. HELP!

I have buttons at the moment, one to play game, and one to go to instructions. When I play the game the loading is smooth, but when I press and load the instruction Scene the loading is not smooth.

Smooth loading when pressing play game: https://gyazo.com/6a2df9c66a193a057c8cc0001a1802c4

Not smooth loading when pressing instructions: https://gyazo.com/9e60157ed6f6334a5764f0e46e4c04e1

I would be very happy if someone did point me at the right direction here. I think it may be that the one canvas is rendering infront of the other. I tried to make a script onload, set z position to -1 because someone said a lower z position would render it infront of the other canvas but it hasn't work.

Here is my load on click script:

     Color Visible;

     private bool fadeoutok;

         if (fadeinok)
         {
             FadeIn(ScreenImage);
             FadeIn(dotsImage);
