Minecraft mobspawning bugged?

Hello in my Minecraft Vanilla world (Java) the mobspawning is totally booked. I built a house in a mountain in a Minecraft world and lit it well. However, whenever I come back there are lots of monsters in my house… Often creepers too, who then blow everything up! I looked in F3 to see how high the LightLevel is and it says 0 everywhere for normal daytime brightness as well as for artificial sources. How can you fix it?

PS: I've built several houses in different places and it's always the same.

Do you use a shader, or generally Optifine

Pe

Yes

It could be because some shaders change the lighting and that's why it is so. I had it once, but everything was dark with me, but nothing has spawned. Otherwise I have no idea why that could be. Try without Optifine, even if I think that's not because, it could be.

As I'm using the BadLionClient. Optifine is already there as far as I know. I will try that then, but is there another option without activating it?

Ah Badlion. Otherwise try to start Minecraft via the normal launcher. As I said, I actually know my way around mc, but my brain is just stalling. Do you have that on other worlds too?
