Creo Schematics - Updating a BOM Table

Hello,

 I have an existing P&ID drawing created in Creo Schematics, and it has a BOM table as shown in the attached Image1.png file. I am trying to update this table to change certain information on it. When I tried to right-click this table, and select Properties, I get an error message as shown in the attached Image2.png file. Is there a way to fix this issue?
