Photoshop Brush keeps turning into eraser?

Ever since I updated to PSCC 2018 I'm having problems with my brushes.  I created a new brush yesterday and used it and everything was fine.  I then opened another document and wanted to use one of my basic soft brushes and everytime I click on the brush tool, I see the brush I was using yesterday which was a dog bone.  When I click on the brush to select a basic brush instead, it then all of a sudden goes into the eraser brush.  I can't seem to use a regular brush anymore.  I've never seen this before.  Anyone have a solution?
