scrollview Menu icons

First of all i want to apologize in advance if this is not the right part of the forum to post. I'm new to this and i am a little confused. I also want to apologize if i make any spelling mistakes (or other kind of mistake) as english is not my native language.

So ia have been learning unity for some months now, and i am currentlty trying to make my first attempt at making a whole game. I did a menu using a scroll view and a prefab slot for the scroll view. I also did a script that adds a slot with the info and sprite of items when they are found. The problem is that everything works fine as long as i am not in a fullscreen. The slot's size is correct, however when i try the fullscreen mode its size is changed and made way smaller than it should. I have tried to tweak the slot's options but nothing seems to work and i feel a bit frustrated. I feel like this is probably a noob error, but as i am a noob i can't solve it on my own.

I will post some photos to ilustrate my problem but if any code is needed i will provide it as long as i am told how to do so (because i don't know how this forum works)

Also thanks in advance to anyone that reads this post or that tries to help me in any way and again, i apologize if i am breaching any forum rule, i am noob to all of this
