Sorry, I'll delete my post.
(EDIT... I can't edit nor delete my own post... bleh)
I did that in many lines, I can't replicate now. Maybe it was because of the sequence how I did it...
I went to lyrics, to replicate... then I decided to remove the round brackets and put it back and the problem is gone and not being able to reproduce.
The case was like this:
[01:23.45]*(here goes my lyrics in [Bm7]bold with an inline chord)*
It would show the stars rather than make the whole line bold. The chord was properly identified and placed above the line. Was only the markups for bold that I had to do a workaround like this, and then created the visual effect I was looking for:
[01:23.45]*(here goes my lyrics in* [Bm7]*bold with an inline chord)*
Thanks Lishy
