Layer groups should come in as nested comps. Try opening the nested comps (pre-comps) by double clicking. Other things can cause layers to come in with larger frame sizes but it is hard to tell what may be going on with your PSD without details.
The PS groups come in as nested comps, but when you go into them, they have the dimensions of the psd, not the PS groups. Some further explanation here: http://i.imgur.com/gzqicjB.jpg
If you try and crop the "Group 1" nested comp in AE to 376x376 (like in the screenshot), you get the weird flickering like I showed in the previous video, and once you save that, the "Group 1" comp has moved positions in the parent composition.
Any response to this? Neither of the above are "Correct Answers" even though they're labelled that way.................
