New page tab has unwanted hyperlink/underscore attached

I’ve noticed that after adding a new page, an unwanted link gets attached to the tab (I’m using the Ocean Mist theme). You’ll notice the “Maps!” tab on my site has an underscore that proceeds it that links to a random unestablished page on my site. There is no space or underscore when I created the new page tab. The main link works fine but I’m trying to get rid of the annoying little underscore.

I think it has something to do with the fact that I’m linking to an external site (another instance of WordPress that I set up). I have another tab that created with no problems, but that’s an internal link.

My site is spatialscrawl.com and the Maps tab is linking to spatialscrawl.com/maps/

I created this link by adding a new page and entering HTML link code as the title and leaving the rest blank (as recommended by others to accomplish this)

Any help is appreciated
