Gray bar under the player avatar

Hello! :-) I made sure to double-check everything before posting, to make sure that it was not related to the browser. As you can see from these two screenshots, it appears as a gray bar under the avatar. It pushes up all the icons and (to my knowledge) there's no way to remove it. I tested on Firefox and Chrome and the issue remains. The funny thing is that it's related only to one campaign while the other one is fine. Do you know how to get rid of it? It's not a major concern, but still... Thank you in advance for your answers! :-)

That's the Macro Bar, where macros defined in a Journal entry's Abilities will show up if Show in Macro Bar is checked. Perhaps you have an Ability with that checked somewhere?

Wow, Andrew! It took you less than a minute to solve it! XD Yes, I'm trying to implement some mod in my game (obviously I need a lot of practice, it's the first time ^^;;;) Thanks a lot! :D
