Hi,

I think if all of your text frames are applied with basic text frame object style (please check object style panel), then you can edit the style by double clicking it and then Go to –>Text frame general options and check “Balance Columns” on the right side of the panel. Maybe it will resolve the issue. Else you have to create a new object style with “Balance Columns” attribute and apply it to all text boxes with find/change.

Thanks
