text below Roman Numeral Analysis

Thank you for your reply. I was able to add ‘staff text’ below the RNA.
The inspector allows me to see that the text I added above the chord symbols was a ‘text box.’ Apparently, when I dragged the text, I didn’t drag the box, as it is still visible, and seems to be adding unwanted space between the text and the chord symbols. Was ‘text box’ an inappropriate choice? I thought by dragging the text I was dragging the box. Might I have inadvertently dragged the text without dragging the box? File attached.
If I click on the text, the inspector tells me it is ‘frame text’ and if I click on it a second time, a thick-lined grey box appears the same size as the text, but if I click on nothing, that grey box disappears, and there is a different thin-lined dashed grey box that is always visible, but in a different location. The inspector tells me it is a ‘frame text’ box, but the frame text is partly outside that box. If I try to delete the thin-lined dashed grey box, the frame text is deleted also. Do you know what I may have done in error to cause this, or what I could do to avoid it in the future?
