BOM not updating details, assemblies custom properties

I have created a BOM with custom properties to be used for myassemblies. I have used this BOM, as mentioned, with SW 2007 andthey worked fine. Now the same BOM are not updating the customproperties in SW2008, S.P. 3.1, my box "Automatic update of BOM" ischecked in my options.
I have to open individually all details in order to update my BOMcustom properties.
Is anyone experiencing the same behaviors?!!!
