Script deployment fail

I have created a simple script under Default.LGF:

*XDIM_MEMBERSET CATEGORY=ACTUAL

[#HV9L_CALC_S]=[ACCOUNT].[HV9L]

after that I go to "Modify Model" > "Process Model" and the result is what I expected.

However, after I modify the above script and Process Model:

*XDIM_MEMBERSET CATEGORY=ACTUAL

[#HV9L_CALC_S]=[ACCOUNT].[HV9L]*900

I don't know why it doesn't work. Even I remove all the logic under Default.LGF, it still calculate the old logic.
