1st beat missing when looping w rewire

When looping a section using Reason as Rewire slave, the 1st beat of the loop is missing 4 times out of 5 (approximately). Anybody knows how to fix this?

Thanks.

No, only that you can loop a bigger section to make it not so annoying!

Yes. I have that problem too.

I usually move the notes just a tiny bit to the right. And all notes are playing correctly.
