My BP just went into his first shed since I purchased him a little over a month ago.

I upped his humidity to around 70-75% to help this, but I have a question since I noticed something today.

He just came out of his blue phase and should be shedding any day now, but I noticed that his eyecaps are dented. I know for a fact that they weren't before the shed and as I said I upped his humidity, so my question is: Is this normal? I have no clue since I have never experienced something like this before.

Any help is appreciated.
