Arranger bug in 10.5.20?

I use the arranger feature in Cubase quite a lot.
In 10.5.10 it worked okay, bouncing when the Arrangement was selected worked okay, but from 10.5.20 it’s no more possible to bounce a full arrangement, there are a LOT of errors.
Sometimes an A part that are supposed to be repeated 4 times only repeats 3 times, and the bounce doesn’t reflect the structure of the arrangement no more.
I have to say that this is issue is with my orchestral template, which is originally builded in 10.5, I hope it’s not the reason.
Can anyone confirm this?

Well I think it was my mistake. Sorry!
Now it works.
