Weird lighting bug

So every night on my world I do a daily path of where I kill hostile mobs. I’m on that path for 10 minutes and I travel 300 to 400 blocks away from my house, when I arrive back home, it’s dark in places where I have torches.

Expected Result: 

To travel 300 to 400 blocks and not see the wired light issue.

Even though this issue is minor, it can sometimes be annoying to fix by placing a block and then breaking it to get the regular lighting back.

Ps.

I have a cave base, I am wondering if it’s only caves that get this issue and not houses built by a player.
