This seems to be an issue/bug with morphs saved in the scene. I think if you select the clothes, Fit them to None, then fit them to the figure again it will work (for that session). A more permanent fix, for now, is to use File>Save As>Support Assets>Morph Asset to save out the morph, but then it will be available on every figure you load (make sure the default value is 0 before saving).
Please make a bug report for this issue https://www.daz3d.com/help/help-contact-us - if nothing else that should ensure you get a notification when it is resolved, or a better work-around/proper workflow may be suggested.
