Why Landscape Brush is dotted?

Hi there,

I created a tiled landscape in 4.23 and currently I’m working on 4.25 with new layer system. The problem is my sculpting and painting brush is now some vertex showing dots instead of that famous radial brush. I resampled the landscape but it’s still the same. What can I do to have my brush back?

Thank you

and new landscapes creating with 4.25 are ok.
