Hostile Mob Spawning in higher light level issue

After the 1.16.201 Hotfix I instantly noticed a new bug.

Hostile mobs such as Zombies, Skeletons, Creepers and Spiders are now spawning in my fully lit up spawn/town area.

It's getting to be a real issue as now I can't stay up during the night or I'm risking my buildings getting blown up by a creeper.  I've already had to do some repairs. 

I even had a Zombie spawn inside of my house.
