I found the "beat resolution setting" has serious problem.
1) start new song.
2) select 8 beat style, Bossa2 for example.
3) set triple resolution at the third and fourth beat of the first bar.
4) put a quarter note at the third beat.
Then you will get extra "tie" mark.

I think this is very serious problem and one of my friend confirmed it has also happened at his BIAB2013.
Can PG-Musib fix this? Or Should I post this in "WishList"?
