Hostile mobs are spawning incorrectly

As mentioned in the summary, hostile mobs are sometimes spawning even in sufficiently lit circumstances. I've tried placing torch on every single block but it still keeps happening. A creeper exploded while I'm in the crafting screen in my house, which messed up everything. That's kind of annoying. It's a good thing that the spawning mechanics is getting more like Java edition, but it's a bit too much, mobs are spawning like crazy. Please lower the mob spawning rate (I don't know if it's called that.)

Thanks
