If the 2-sigma cleaning is causing problems for your case, did you try disabling it in AIJ? If not, go to Image Display > Preferences > "Ignore pixels > 2 sigma from mean in photometer background region". If this option does not solve your problem, please let us know the algorithm you used to compute the background that is giving lower noise than AIJs current two background computation options.
