If you need to sort your Field Sections into a view that works better for you, this can be done by going to the hammer icon and selecting Field Editor.
From there, click on the Groups button and select Sort Groups. This will open a new window that shows all of the Field Groups and the Field Sections within them.
You can drag and drop any of the sections by clicking on the six dots to the left of the title of the Field Section. They can be moved up or down within the same Field Group or moved to a different group entirely.
After you have everything in the correct columns, click on Close in the bottom right corner.
