I have created a group of say 3 forms, copied that about 100 times and grouped them into larger groups of 10 -15 shapes which I again grouped all together. Once I ungrouped the large group I expected the ungrouping to occur only on the first level as it would in Powerpoint. However, every last small form was ungrouped so I need to manually piece all the groupings back together. This is hugely annoying and a time killer. How can I avoid this?

If this is not a user error it’s a bug in my eyes as other software that works with groupings behaves differently.
