Button Only Partially Clickable Error

I have a very strange error in which I can't figure out why the button is not clickable for the entire 'red area' of the button. Attached below is the images of what happens. Whe

Solution 1:

Ok turns out I figured it out, thanks to the answer here: Only the left half of the button is clickable in IE

The image of the pool cleaner in my design was getting in the way because it was positioned absolutely.

By adding the CSS to that element pointer-events: none;

it fixed the issue.
