Are you saying that when you unstring the bow, some twists/bunching up occurs near one of the limb tips? If so, it means that you have the string twisted too much. I.e., your string was too long to start with and you had to twist it too much to reach the appropriate brace height. If you have a flemish twist string, can untwist the string and redo one of the loops, making the string about an inch or so shorter. Or buy/make another string that will be about the same length as you have now but with fewer twists in it. Hope that makes sense. Good luck.
