Illustrator on iPad mirror repeat and isolation mode

I created a drawing in illustrator on iPad and then selected mirror repeat.  It made a lovely mirrored repeat, but I decided that I did not want it and could not get it to undo. The undo is grayed out. Here where it was fine when all of the layers were present before.  It also seems as if it went into isolation mode, or at least I think it did since the layers no longer show all of the pieces of my drawing.  Layers only show the mirrored repeat. I would hate to lose all of the lines I created. 

Is there a shortcut or anyway to get out of isolation mode, to undo a mirrored repeat, or is there any info on tools that is available beyond the quick tutorials for illustrator on iPad?  I am using a brand new iPad pro and a second generation pencil. Thank you.
