I’ve noticed that when using a horizontal repeating group with more than one column, the horizontal scrollbars do not show and only displays one record. When either using one column with a horizontal region or any vertical option, the scrollbars show and display all records.
In the attached example I’ve created these three cases that demonstrate this. The horizontal region is for the children in each family.I can’t think of any reason why a horizontal region would not need to scroll and/or just display one item, so I’m figuring this to be a bug. But if not, please let me know.
