Soft body jiggle physics?

So I tried doing soft boy jiggle as normal, with the proper vertex group and whatnot, but when I add soft body, the part of the mesh set to 1.000 on the vertex group still jiggles. (not as much as the part thats SUPPOSED to jiggle, but it still jiggles none the less.) I think its because of an update because the first time I tried it (back in 2015) it worked fine, and now it doesn’t. Can anybody help with this?
