STB 5 - Un-Not auto Flatten brushes

Good day, It’s a two step process : First, you select a brush that you’ve decided “TO BE auto-flattened”. Works pretty well. Second : Then youI select a brush that is specified “NOT TO BE auto flattened”, this brush keeps being in the auto-flattened mode. I have to manually uncheck every time the box for it TO BE NOT auto-flattened again. Bummer. Could you please check if you’re experiencing the same behavior ? Thanks

Yes you are correct in your observation. The auto-flatten property does not seem to save the ‘NOT TO BE auto-flattened’ correctly in the custom brush/tool properties. This looks to be a bug.
