I had this before and lost it during a revision and can’t redo it. I put in Tempo I and then hit shift+t and added the metronome marking and when I hit enter Tempo I disappears. I tried reversing the problem and again the last entered disappeared. Any suggesttions?
Unfortunately you cannot currently show a metronome mark as part of a tempo item that resets back to a previous tempo. We will add an option to display the metronome mark that the tempo reset will produce in a future update.
