Issue with new fields list update

Good Afternoon,

Today I noticed that after the new update to the fields list I can no longer create hierarchys in calendar. For example, I was easily able to drag certain fields over another to create a hierarchy. Now, that is no longer an option with the new fields update. Can I turn of this new fields list off like previously before the update made it default to this?

Below is a snip of my old report that I already had a hierarchy created but I can no longer recreate this. If I try to drag quarter over year, it no longer works which is a huge issue for me for my future reports.
