Problem with the Character Spring

I downloaded the 2.8 Blender splash screen file (which is free). However when I tried to move the Character Spring, the jacket didn’t come with it.So it took a couple of weeks to figure that it had to have a mesh deform modifier but I am still having a bit of a problem with it.I have tried a lot of things to try and get those little spikes back but without success. Is there something that I have to do to get them to where they should be.
