what you might need to do is tie a small serving like a peep sight above and below each leech this will pinch the string a lttle tighter on the leech so they won't fall off.
I don't think he meant "leech" .
Unless the product is defective you may have accidentally smudged the limb with your fingers after cleaning it and the adhesive just didn't take . Try to reattach it with some fresher adhesive or return it .
