Your pgo has not been changed to 20 fps.
We used to say that you need to edit the pgo file, before you layout the phrases.
so
1) Create a new pgo fiel from wav file
2) Paste in lyrics and do initial layout.
3) Exit and edit the pgo file from 24 to 20 <======= important step. Do this before dragging everything around.
4) Go back into papagayo and do the real layout, save
5) Go to xlights, use pgo file in papagayo tab
here are first few lines of your file.
