Thank you! I posted it there too. Its strange and i’m not sure of the reason its happening.
to add some more detail:
The hamburger is sitting in an inner section column, split 50/50 with an image in the left hand section.
When I stack them on top of each other, even though the navbar is in the same place on the right (just below the logo now), it works fine and everything is visible. Its only when they are side by side it cuts off.
Thanks again for pointing me over there.
