fermata doesn't attach to note in first voice

I need a fermata on a note in the first upper voice, but it can’t be done. The fermata appears on every other note in the 2 piano staves, but not on the note I need it:

You can’t have a comma and a fermata attached to the same note position, for some reason. If you attach the comma to later in the rhythmic grid (a quaver/eighth later in my case) the pause returns. See screenshot.
