This QuarkXPress processing message occurs if Q++Studio encounters a Sara which uses a regular expressions where a specific capture group is replaced, when using QuarkXPress 8-2017.
This run-time message would have been preceded by a corresponding design-time message.
To be able to specify that the replacement of a Sara only applies to a particular capture group, you need to be using QuarkXPress 2018-2025.
