Data Exchange Integration Running Business Rule not in Options

Hi, we're using Planning and Budgeting in EPM Enterprise.

I've created a data exchange job which is working and running as expected - except for the fact that when I check the logs, it's running a business rule after the check stage that isn't selected in the business rules options screen. Has anyone seen this before, and is there a way I can fix this without rebuilding the whole integration?

I've tried deleting the offending business rule (with a view to recreating it) but that just causes the integration to fall over altogether, when it can't find the rule.

Many thanks
