I changed my drawing view to be at a slightly different angle. Now some of my balloons are in space or on the wrong part. I cannot drag the balloons to a part and have it update; it still looks at the original part.
In the pictures below, I drag balloon (3) to the screw, which is the screw's item number. It changes to (17), which is the tubing's item number.
tried to rebuild
deleted the balloons and BOM and made new ones (automatic and manually)
deleted the entire drawing and created a new drawing
