Menu Drop down Hidden behind certain Page WCvendors. & shop page duplicating

Hi

I am using your theme and love it. Have had no real problems creating what I think is a lovely site because of your theme. However, getting close to going live and there are two things that are wrong and would appreciate any assistance.

Firstly, I have woocommerce installed and a multi-vendor plugin called wcvendors pro. Everything works great apart from two things.
There is one page on the site where the navigation menu hides behind the page, see gif animation for example.
On all the other pages the navigation display perfectly. I am at a loss at how to fix as I can barely code.
Navigation drop down hides behind certain page (created by wcvendors*)

The second problem is that I have some customisations on the main product archive(shop) page, and they repeat on the vendor shop pages stores.

Main Shop Page

Funnily enough, this did not use to happen and all my shop customizations were on the product archive page. I’ve checked and tripled checked my vendor paths and settings but they are all seemingly right.
I also have some vague recollection that this duplicating of text appeared, but I could be mistaken, after the cart in the header bug was fixed.

This is the vendor store that has the same text displayed as on the product archive(shop page)

Any help would be much appreciated especially with issue 1. I have a workaround for two

*I have yet to check with them regarding this. However I have checked with issue two and wcvendors claim that the theme is not differentiating between the archive and vendor shop pages. Which is why I am lumping these two together, just in case they’re related.

Thanks.
Wow long winded or what!
