I don't use SE but it sounds like you have not regenerated the model. As with all parametric solid modelers, they allow you to change dimensions on the fly and will mark the dimensions that have been changed either with ( ), [ ] or ___. This is a visual cue to let you know that you have to regenerate the part. Doing so will update all dimensions and display the part properly. Check to see if this is the case. There should be a regen icon to do this.
