Edit Multiple Properties in Bom has started to update Configuration Specific rather than Custom

Hi All

Working through a lengthy indented bom, and I update a lot of values at this stage using Edit multiple properties.
However this morning its been updating the configuration specific ones (which I have none and parts usually only have one or 2 if sheet metal, configurations)

This is a pain as It means I need to open each part to update the custom propertys.

I've tried  the options in the bom for part config grouping, I'm sure its a tick box somewhwere?

Any Ideas Ladies and Gents?
