I really like how the bar looks, however I have an extra non-clickable space in the bar.

Without ElvUI active the minimap looks like this:

Could it be possible that there is an extra space for the "What-Shows-Up-On-The-Minimap-Selector", but ElvUI hides it?

Hi,

Strange stuff. Could you check how the mini-map looks when you enable ElvUI but don't enable the ElvUI_Enhanced_Again add on?

sure,

Okay I figured out what went wrong.
I'm using Trinketmenu, which has an option to hide the minimap button. If I uncheck that the button shows up and fills the middle slot.
