Common Units Install Error

I am trying to install TadvPanels with TadvGridPack, with error that advStylesIf.pas is contained in both packs. I removed advStylesIF.pas from both packages, and installed in a new package named  "TMS_Common" and installed the common package. I then added TMS_Common to the "requires" list of GridPackd2010. When I attempt to install GridPackd2010, I get error message "Never-build package GridPackd2010 requires always-build package TMS_Common".  How do I fix this error? I cannot see any options for building/never building packages.

Link options of a package are under package options, description, build control
