Sounds like you got some bad paint that didn’t get mixed properly, or the pigment was bad.
You CAN paint over oil based paint with either another oil-based paint, or with acrylic latex paint. You cannot paint oil over latex though. Just give the surface a light scuffing with a sanding block, so the paint will adhere better. Or if you wish, you can sand all the old paint off and start over. It’s your choice.
