You have chosen to unify the analyses belonging to a group. This means that for the current group, the group's versions of all of its gates will be applied to all the samples. Any special modifications that you have made to any of the samples in this group will be lost.

This will be done for all samples in the group, and for all analyses belonging to this group.
