There are shell fix scripts included with most of Meipe's and many other vendors grafts with shells, however as the issue is how Daz Studio applies surfaces to shells. By default Daz Studio adds the surfaces of figure and all grafts attached to figure, but Daz's use of Geo Shells and a lot of Vendor's usage of shells differ, Daz has pointed out there should be one shell and one shell only for Base figure and all grafts. Most Vendors are including shells/shell presets for each graft, and as the shells stack and Daz Studio adds graft surfaces on each and every shell it requires, running a shell fix script on each and every shell to turn off the extra surfaces it is adding, also the more shells included the more offset clashes you'll have as well as all the shells are loading in at same offset distance so it causes Mesh Collisions between shells (Often shows up as black lines on the figure, where the shells surfaces issue shows as white where there isn't surface information on the shell)  

However as long as Daz's stance is the geo shells are working as intended, there won't be a fix, because to them there is nothing to fix. It is the vendors that are using the shells wrong and Daz has said they have no intention to fix what they aren't seeing as an issue.

So really options are running shell fix scripts on every shell in the scene to turn off the "extra surfaces" on that particular shell, or manually going into each and every shell and turning off the "extra surfaces"
