Thanks for the links, Pipeline. I'm sure they will be very useful. But my main problem is finding the lyrics that used to be there and that are no longer displayed at all.
I haven't read through the above posts so I don't know if this has been mentioned or not. Just in case it hasn't...
On your chordsheet, has the bar lyrics layer been activated so that the bar-based lyrics are visible (see the 1, 2, 3 on the upper image below)? If your chordsheet view is different from mine, use CTRL+T to switch views.
When bar lyrics are made visible, they will show up above the chords on the chordsheet (see the lower image).
