Can't get editing subtitles in BSplayer Pro 2.28 working

[matjong]

I just bought BS player pro 2.28 since I heard it was possible to change the frames per second of subtitles there.

When I try to edit the subtitles it only change the framerate of the first text (while all lines are selected) the other lines are just showed 1/100 second later because the first frame is displayed later. All other lines still have the old framerate.

Is there anything I have to do to get it working or is there something wrong in this BSPlayer pro version?

I hope there is somebody who can help me with this.
