Did you take hydrometer readings before racking to see if fermentation was complete? If you didn't and just arbitrarily racked, more than likely fermentation was not complete yet, and you interrupted fermentation when you moved the beer. Because of that the yeast is re-krausening the beer so it can attempt to finish the job. It's quite common in first time brewer's batches who don't wait til fermentation is complete.
The thing about moving your beer so soon, is that if you've experienced a 72 hour lag phase with your yeast, then in truth your beer's only been fermenting for 3-4 days when you move it. Often not quite enough time for the yeast to do their job completely.
It should be fine, but in the future don't rack the beer based on a calender, but on 2 consequtive hydrometer readings, three days apart. And I recommend folks don't even take their first reading til day 12, and the second on day 14. It gives the yeast plenty of time to finish, and clean up after itself the byproducts of fermentation that leads to off flavors.
