Noel,
This is essentially what I suggested earlier. Repeats and endings, as well as fake sheet are purely print functions. They do nothing to the underlying song. So looking at the song in notation mode will show you each bar as it is played, not the repeated bar as in fake sheet mode.

Fix or alter the specific bar or bars as needed. You cannot delete or add a bar, only change. You can add more bars, perhaps an extra repeat, or a coda, but you will probably have to adjust the repeat / endings dialogue

Then, as you say, "reactivate fake sheet"
