Button appears in two important locations and feels redundant

I'm building a log in page but ran into an issue with my nav bar. As you can see the "Log In" button appears in two locations.

What's the best way to approach this? To me it looks odd to have it shown twice, yet its a necessary part of the nav bar.

I can correct this by removing the button for just that page...but then that feels like a complicated solution because it requires modifying template code with an if statement.

What should be done here instead?
