problem with step mode in ultrabeat

I use step mode in ultrabeat (when everything becomes yellow). Lots of tweaks are done in step mode, and everything sounds correctly. But after reopen the project some voices sounds like they are in voice mode, not in step mode, even if the step mode is on.

This problem could be fixed by clicking on that voices. But there are 25 of them, it is really annoying. Could some one tell me, why does it happen? Thank you…
