Zbrush extracted mesh causing doubles and inverted normals ?

I'm trying to delete part of the mesh I extracted from my body mesh to use for clothing, when I try to delete it the inside of the mesh loses thickness, see the rim of the sleeves compared to the deleted area, and it also gives this double/ inverted normals issue

I try to extract instead of deleting given it's not working and I get doubles on the inside but with thickness, see 2nd image

the only way I can think to solve it is to extract the cutouts of the clothing on the original body but I would like to understand why when I extract from the original body mesh the result is fine (1st image) but when trying to achieve cut outs on the extracted mesh I'm getting these issues, any help would be appreciated please

    By now you figured out a solution right?
    i try to fix this with inflate and dynameshing to a high % perhaps 4096 might work, click it, then remesh to a "quaded retopo".
    and adjust as needed, probably a good "cloth" sym over your "basemesh or design", will sort the issues out, though i've had a tough time getting the cloth sym to play nice. 
    I usually also just do the "time saving thing", of just retopologizing pieces in alternative ("example topogun") software and call it a day.
    Otherwise idk why this happens, perhaps its something to do with double sided masking, https://www.youtube.com/watch?v=G_pEfhDqtZY in this case you maybe did not click it to TURN IT OFF so it would not select the alternative side.  Worst/best guess.
    Also zbrush being zbrush.
    If you did find a solution usually posting it would help others, hopefully this posts helps someone else.
