i have had this same issue and there is a fix, for some reason you cant just use the latest version of jenesis and launch it through imenu
but there is a way to fix it, the problem is i forgot how , i thin i got the answer on the dstwo forum site
i remember i downloaded something , but then i never used it and i dont where i put it , i was still using the old jenesis launched from imenu and it works fine , i never bothered to update to the newest version and to install the fix though
so you can either ty to search the dstwo forum and see if you can find the thread , (good luck)
or you can try using the older version of jenesis that works with imenu
