Why Are There Two One World Festivals?

OK technically there was a World Festival and an One World Festival, but why did this happen? What caused the split wherein now they have two festivals.

Clearly there was a difference, the one in the end of July was much more commercial. There were a lot more vendors celebrating the diversity and kind of food Cleveland has to offer.

The one during the end of August was more focused on the Gardens themselves, having them shown by guides who can tell you about them, and raising funds for the 100 anniversary. Cause some of the Gardens look bad.
