CDF Edit feature disappear

Hi Sir,

I try to edit the termOrder in CDF/Simulation Information tab. It works but the new feature disappear when i restart cadence. 

There is a data.dm file checked in for the target cell. 

Does it mean cadence reload the info in data.dm every time after reboot, so that CDF is overwritten? 

How i can change permanently termOder through only editing CDF, but not recreate the symbol again (since the cell is from 3rd part, not able to be checked out).
