This is still an issue (Designer 1.8.6): once I change a stroke to texture style, I can no longer change it back to fully-configurable solid or dash line style. It almost seems like the solid style works (the stroke loses the texture effect), but I am unable to modify the stoke pressure any more and opening properties just shows the old texture style instead of the solid one; and changing to dash line style does nothing at all. This is really frustrating as it means if I change a curve to texture stroke (either accidentally or to test how it looks), I can never go back to fine-tuning the solid stroke version, without just having to remake the curve, which is not something I'm willing to do for anything more than the most simple curve design. Now if I want to test out texture style, I need to remember to create duplicates of all my curves ahead of time to avoid "breaking" them. When will this be fixed?
Never mind - after trying for several days over the course of a few weeks to reset the stroke styles on my curve layers, I discovered that I can create a fresh stroke via Studio > Appearance > Add Stroke. The new stroke can be fully modified as a solid or dash style. It's still frustrating and confusing that I can't apparently switch between styles on a single stroke, though.
