Uniform plugin and select box issue

Uniform plugin and select box issue

I am really baffled at this issue because I have no idea where the problem
is at, nor do I know where to begin.
I have two selects as you can see in the image. The one to the left is
fine but the one on the right is much smaller than the content within it.
I personally believe the issue is with the plugin but again, I don't know
where to look.
Here is what I've done. I've disabled the plugin and the select box comes
back to full size and the onchange event works as expected. When I enable
it again, the onchange is more like a mouseup event because the instant
you click on the select, you're forwarded over to another page; it won't
allow you time to make a selection.
Can anyone shine a little joy over this way, please?
