By default, the version 2.1 brings the logical grouping of all the objects you create with the Head and Body Tool (see more info in Text frame tools). Moreover, the other objects you add manually to such logical groups, if they overlap the members of the logical group, are added automatically to the same logical group.

In case you want to, you can turn off the logical groups handling for all the users by adding to the EditorialConfig the following line:

<Item Name="glbUseLG" Value="false" />

The line does not exist in the standard configuration, therefore, the logical groups handling is turned on.

IMPORTANT: To make these changes available to the GN4 users, after you saved the file and imported it into the database, make all users log out and log back in.
