When I insert a BOM table I need to edit the standard parts descriptions (e.g. change "ISO 4762 M6 x 16 - C" just to "Skt Cap M6 x 16". )  Up to last week I could simply double click on the BOM text and edit it, and I can still do this for tables created in earlier drawings.

On new drawings I create, double clicking on the cell text has no effect and won't allow me to edit ( standard Toolbox parts only - others can still be edited).

I have tried overwriting the .sldbomtbt  template using the older files, but it doesn't help. Have I set some sort of switch in the software, and how do I reset it please?
