Cubase 11 Grouped channels out of sync

Hi,

I created a KICK, Bass and 3 percussion tracks. The kick and bass are midi instruments and the percussion are samples. They all play in sync.

When I group the 3 percussion tracks, the group is out of sync with the kick and bass. When I group the Kick and Bass and not the percussion, they also play out of sync. There’s something broken with the group tracks. How do I fix this?

This happens only in v11 and not v10.5
