Brno:

Here's what I have in my "BIAB Tips and Tricks" file on copying bar based lyrics:

INSTRUCTIONS:
- Highlight the bars in the chord grid for where the "source" lyrics are located
- Right click INSIDE the lyrics layer of any selected bar (don't highlight the lyrics layer)
- Choose "Copy selected bars" from the dropdown
- Left click the chord grid area for the start of the "destination" for the lyrics
NOTE: make sure there are NO existing lyrics for that bar
- Now (don't highlight the lyrics layer) right click INSIDE the lyrics layer where the lyrics are to start and select "Paste"

Let us know if this doesn't work for you.
Good luck!
