The problem here is that you're duplicating the existing titles for the static entries and you're losing all the help that text that used to come along. The point of the BEHAVIOUR thing, further mapping to either static or dynamic preemption, was to avoid that duplication and keep the same titles and help for the three behaviour, whether static or dynamic.
Thanks.
