so if you have installed some MCM or JCM , then it work genesis, you can check it,
the actual hidden morph which work jenesis must be reffered genesis root, I think,,
just select genesis with keep bending in scene tab, and when you bend genesis,
go to parameter tab, then “Show hidden properties” first, by parameter tab option menu
(bar and small arrow small squear icon, you can see top edge corner on parameter pane)
and check currently used.
you may better with check character morph ,
because, they sometimes original mcm which reffered to the character morph..
so the problem may happen, when you only use the character morph and bend.
but I think, as mjc1016 said,, it is usually problem areas, even though you remove some mcm or jcm,,
so I decide, now whenever I feel problem, just make simple morph (with no ERC) and apply it,
for the scene only ^^; though it can be useful only for the character and for the poze,,
