In my villager trading build, I have a zombie in the back that keeps de-spawning when it has a name tag and a item in hand. I've tried with many zombies and it keeps happening.

If you used Optifine, you're probably experiencing MC-193509. Uninstall Optifine to resolve the problem.
Are you sure this happened in 1.16-pre5 or did it happen in another version?
