Hi folks, I'm really hoping someone can resolve this for me as it's been driving me crazy. Either I'm doing something fundamentally wrong, or there's something seriously amiss with my installation of Photoshop (currently 21.2.4).
The problem is described in the image I've included. When I atttempt to modify the brush settings on any individual brush preset, it affects ALL installed brush presets equally. This happens regardless of whether the preset was created from the 'Brushes' or 'Brush Settings' menu and only occurs since I updated Photoshop to version 21. I have also reinstalled version 20.0.10 as a test and this problem ONLY occurs with the newer installation.
Any ideas? Has anyone else encountered this and managed to resolve it?
