Please help!

I have a report where the first page prints perfectly but the second page repeats 1 section (1 of the group headers) from the first page and it prints the same group header from the second page underneath the first one. So on the second page I have 2 of the same group headers (1 from the first page and 1 from the second page)
The third page prints perfectly what the second page should be.

To help clear this up - my reports are on different classes and the second page will repeat the description for the yoga class and underneath it will have the description for the painting class. The third page will have all the correct info for the painting class (price, dates, times, etc) as does the first page on yoga.

Any ideas how to solve this problem?
