Navigation button issues

Hi there, I’ve been using this plugin and it’s great! Exactly what I needed for my website.

I’m using phpBB inside a WordPress page and the Mantra theme for WP.

The issue is that when I enable the forum page in the WP-United settings it created a nav bar button called Forum. I can then organize that button as I like but when you go to the forum page the button will appear exactly as when you enable the forum page.

The navbar staying the same on the whole site but then a different position in the forum page makes it look really messy and unprofessional.

Is there a way around this?
