HELP - Nav Bar Menu in Header

Hi, I am trying to add a new nav link into the template I have bought, but when i add a new navlink it bunches up next to another one (see portfolio after services) and i can’t seem to get the spacing correct. I also need to re-arrange the order, which is the best way to do this?

Could someone please advise on how to do this effectively?

Apologies - I am a complete newbie to Webflow!

Thanks in advance
