I don't know if this is an issue others have had, as I haven't been able to find any help anywhere for it. I've been trying to paint a project and while it worked as it was supposed to very briefly, something went wrong. I try to use the watercolor brush tool, but as soon as I put my stylus tip down, the brush changes to the blend tool and refuses to paint. I have looked through all of the properties and tried everything I could, but I cannot figure out what is wrong. Does anyone know anything that might help? It would be much appreciated, since I can't continue my project until this is fixed.

Thanks very much!
