Can’t proceed to the next stage

I won the 7-10 battle but it doesn’t let me proceed to the 8-1 stage on the infernal world.

My id is dge4m9

Could you help me solve this issue?

And here is another possible bug.

Sometimes the enemy stays in the weird position even though when they are not attacking.

Hi, thank you for reaching out. Inferno 8-1 is not available yet. And thank you for the bug report, we’ll look into it.
