If you skipped learning how to make a proper loop then ReCycle will just work off whatever incorrect length you cut your loop to, and so it will use that incorrect information to determine the tempo and grid, but even if you did calculate the correct loop length based on tempo you might have issues if the source material contains swing.
Without having the correct length (and therefore the correct tempo) to begin with you will need to drag the right locator around until the grid fits, but like I said earlier if you have swing in your source material then that shit might not line up anyway.
