Distance selector style 'bug' in Nearby Events page

Hi there

I have a situation where the distance selector (drop down) in the Nearby Events page appears to have a styling conflict/bug as the drop down appears to display facing 'left' when it should face right, so you can see the distance options.

See attached screenshot

Before I attempt to fix the css, please can you check this and see if this is a bug that needs to be fixed in core code?

Thanks
Paul
