I would add 9.2 or 9.21. What I did when I first noticed this on some of his tables was to make a new bumper, give it all the same settings. Then delete the old one, rename the new one to the same thing. Also note the x/y position settings, and put those in the new object after deleting the old one. Note: Copy and paste will not fix this! It has to be a new bumper with all the same settings. It's a pita if you know vp. If you don't I'd just add 9.21 and be done with it.
