Transferring of Activity Progress

Hi,

Im having problems on importing activity progress from my "Progress File" to my "Working File". I've tried doing the "P6 to Excel to P6" importing/exporting method. 

In the process of exporting my "Progress File" to excel, I called out "Activity % Complete" as part of my excel template. Then, it reflected as "(*) Activty % Complete (%)" on the excel spreadsheet. it was mentioned in the forums changes made on those with asterrisks (*) will not be reflected once imported back to P6.

Can you guys suggest any method/s on how to work around this?

THANK YOU VERY MUCH!

btw, I'm using P6 V6.0
