In order to make this work, you need a combination of following shape data on the child shapes (= buttons on which you applied the 'Execute' shape data):
This should link the shapes to the Execute actions instead of acting as an element navigation button.
Does any of the parent shapes have the "enabled=false" shape data? In that case, this behavior is inherited by the table row shapes. You can work around this by adding "enabled=true" to the shapes, this will override the inherited behavior.
