How to remove the extra dropdown arrow icon on nav menu

Hi Tom,
I'm new onboard and digging how quickly I can build a site and control the style. Very cool! I bought the premium to get all the features.

I'm just having one problem that I didn't find the answer to here.

1. the nav menu displays two arrows for the dropdown menu when only one is required
2. In the mobile version this is also the case... but with way more padding than necessary between the listed menu items.

You can see what I'm talking about in the screenshot linked below.

Any idea how I can fix this?
Thanks!
