We are using version 2.7.4b. Registrants in some categories receive a discount when registering as individuals. We have a flat rate set for groups, the discount should not be applied to individuals in the group registration, but it is being applied. This worked correctly in previous versions (without the flat rate group option).
Sorry, but you'll need to submit a ticket with specific details... what event... what discount... etc. How to replicate basically. No other reports like this have come in so it may be a setup issue.
