Brushes changing into erasers?
I'm not sure what exactly is going on. I've noticed that after using an eraser, some brushes turn into erasers. It's a bit hard to explain, so here are screenshots:
here's one of the default brushes, working totally fine.

here's one of the default brushes that turns into an eraser after I use an eraser.

I've pretty much noticed that the only brushes that do this are the ones that don't have a paintbrush in the upper right-hand corner of their previews.


It really messes with my productivity to have these brushes changing into a totally different tool after I use an eraser. They don't just change into erasers though - after I use one of the kyle webster oil paint brushes, these brushes take on the quality of being oils too. This never happened when I first downloaded photoshop. (Not sure if this is relevant, but I only recently ran into these problems after I opened the program one day and saw that it had deleted all of my custom brushes, and I basically had to re-download the ones I got online from scratch.) Any advice on how to change this?
