The PoE is called a problem because there's nothing we can do about it. You have a lot of book-smarts, but not much wisdom.
No, you're not understanding the PoE.
It's a problem because there's a contradiction.
Think of it like "The Problem of the Square-Circle." The problem isn't that "there's nothing we can do about it." The problem is that the premises in the argument lead to a contradiction,
which means that one of the premises of the argument must be wrong.
No matter how many times I explain this people still seem to think that the PoE is whining about evil existing. That is not -- not, not, not, NOT -- what the PoE is. I don't know how to say it any clearer.
The PoE shows that God can't be omnipotent, or can't be omniscient, or can't exist, or can't be the creator, or can't be benevolent. It shows that if you put the attributes of God: being omnipotent, being omniscient, being benevolent, being the creator, and existing together with the fact that suffering exists, a contradiction arises and therefore one of those attributes is false. This is exactly like if you took the attributes of "being square" and "being circle" and put them together at the same time and in the same respect you end up with a contradiction, and therefore one or more of the initially assumed attributes MUST be false.
It isn't calling for us to "do something" about evil. It's calling for believers in the attributes of God listed to understand that their position is untenable and that they must admit that one or more of the characteristics is false!
