I saw the replies below, and felt I needed to clarify, as your questions haven't quite been answered adequately.
Sta.sh should not contain files that you published to your gallery, unless of course they're separate deviations that happen to have the same file. In other words, it should only happen if you submitted the same file to sta.sh and your gallery. It is possible, for instance, if you're using the new submit page, that you went to the submit page and selected the same file but quit the process several times (instead of continuing on the submission you had started) before finally publishing it - resulting in the file being put to your sta.sh and later another deviation with the same file being submitted once you did publish them. If this is not the case, it must be a bug, so please report it
I'm not sure how you mean exactly it has "switched artist's comments around", but that sounds like a bug too.
When you're experiencing a bug or have another question about dA, it's best to always go to the Need Help? thread as the rules indicate, to see where to go to get help with it - in this case, the Help Desk. This avoids potentially embarrassing situations and false or otherwise inaccurate information being spread
