Dynamics playback issue

Hi, gang!!!

I don't know if it is a bug or is something still not fixed.

Dynamics work when we playback music ONLY when there are a lot of notes into the staves.

If you see and hear my "very wonderful awesome" personal composition (hi hi hi hi), you can note that:

The bars fulled of notes (first 8 bars)... Dynamics work so fine!!!

The bars when I put a repetition sign (last 8 bars)... Dynamics don't work!!!

Well, to be honest, the first 4 chords (on the first bar of the repetitions section) are played with an audible dynamics change. And this change is exactly the same into the next 7 bars of the section. But.. It isn't what we'd expect to happen.

It is the same when we use tr... and other articulations. It is the same when we put dynamics sign into a long time note (a whole note or tie notes).

Is it a bug??? Or... Is some known issue, still not fixed???

Blessings & greetings from Chile!!!
