Unable to make a nested group in 2021 from the highest level tag

hello! I just started using SKP pro 2021 (I was on 2018) and it will not allow me to create a group at the highest level of a nested shape. It seems I have to start at the deepest nested level if I want to create more nested tags. Is this new to 2021? And is there anyway to change it back to how it worked in 2018?
