Creo Hole Chart is no improvement by now

I use PTC software for design from WildFire 3.0 to Creo 3.0,  I am very disappointed for Hole Chart, espacially, the " update tables" function, everything customized return to default setup when you update table,such as merged cell,decimal places, and so on, I am  confused why PTC cannot solve these issues by releasing so many  versions.
