There's no bug. You're doing something wrong. If you show us a bit more

type. To get the scalar variable found in the glob, you have
to dereference the glob as if it were a scalar:
my $g = $main::{$Player{Location} . ::}{Options};
my $value = $$g;
or, as one line:
my $value = ${ $main::{$Player{Location} . ::}{Options} };

If it was a typo

print keys %{ $ref_allTariffData-{$filename} };

For additional

The extreme cases are the easy ones, though. What I'd like to see are
cases like:
foo = 1
bar = 2
qux = 3
