Adding Tempo Marking Into The Header Frame In MuseScore 3

I've been trying to place the tempo marking in the header frame of my projects on MuseScore 3, but every time I try to drag the tempo text into the header, the software increases the space between the staff and the header frame. I have a file in MuseScore 3 where the tempo had no issue being placed in the header frame, but I haven't been able to recreate this instance again. I know that MuseScore 2 also allows tempo to be placed in the header frame. Any recommendations?

The file I attached displays what happens when I drag the tempo marking into the header frame. I would like the tempo to align with with "composed by" text.
