UI Input field detection off

I currently have an input field within my canvas, however, recently I decided to change the canvas settings such that the canvas renders to the screen space of the camera.

After doing this I clicked the input field and there was no reaction, the mouse click only registered when I clicked a small distance under the input field.

*Note* - the input field worked completely fine when I was rendering to the overlay. I've made sure that no UI objects such as images are blocking the input field. Would anyone happen to know what might potential solution would be?

Thanks.
