You have to change the way you build the structure, because it's the source of the problem. Please read all the comments and linked pages again to understand.

push @currArr, %currHash;

This line does not insert a hash into an array. It flattens the hash to a list to be inserted. Use Data::Dumper to visualize the resulting structures. What structure do you exactly want to build? If you want to create a copy of a shallow hash, use

push @currArr, { %currHash };

To create a deep copy, see Clone or Storable.
