Primer chipping on cabinets…. What have I done wrong?

So I started the process to prep for painting some cabinets in one of my bathrooms. I wiped them down and then I used Crudcutter to clean them both the doors and the boxes really really well. I then went in with 180 sandpaper and began sanding down what was left of that light lacquer finish I did that on the boxes and on the doors. And then proceeded to vacuum each door in the boxes, used a microfiber cloth to clean them and then use the tack cloth to wipe them down. And then proceeded to use ZINSSER SMART PRIME brushed on a thin coat so when I woke up this morning after 24 hours, there were certain areas that if my fingernail nicked it, the primer would chip off. So I took 320 sandpaper and sanded all of them again focusing on any areas that were easily chipping off and re-primed. But after six hours of drying when I went to check on them, there are still areas that if I use my fingernail, there’s still a few areas where are the primer is still chipping. So what have I done wrong? And more importantly, what do I need to do to fix it? Re-sand everything? Any advice guidance would be greatly appreciated.
