No Waterfalls?

[Mats59]

Hey, I'm new to REW and have the latest Beta installed. When I click on the waterfall option including the generate tab the waterfall doesn't appear. It says generating waterfall etc, but the graph is empty. Is this a bug? Thanks!

Make sure the range of your graph matches the range of your data, the waterfall may be below the graph range you have selected, for example, so no visible.
