this profile.

themes -> mythic -> layout disposition -> others. 

observe no ability to change the position of the others header.

observe custom header is detached in the layout editor for Correct order Mythic

with frame lock unchecked still cannot move the custom header.

Did you try having Grid2 as the only enabled addon and everything else disabled?

yes n/a

Was it working in a previous version? If yes, which was the last good one?

no

Do you have an error log of what happened? If you don't see any errors, make sure that error reporting is enabled (`/console scriptErrors 1`) or install [BugSack](https://mods.curse.com/addons/wow/BugSack).

no

Please provide any additional information below.

You have to set a border greater than zero to be able to move extra headers defined in the layout editor.

Goto Appearance -> Layout Look&Feel -> Spacing and set a value higher than zero.

Then you can move the headers using the mouse and clicking on the border.

If you dont want to see any border, but at the same time maintain the posibilitiy to move the headers, you can  assign the "None" border texture instead of assigning a 0 border size.

I was so close... I was changing the border size in frames look and feel. Thanks!
