Please to show us the code that sets $freq. Given the code here if it is 'FREE' and @size>=1 then both print statements should be output. So your assertion that $freq is actually 'FREE' is doubtful. Incidentally a more idomatic and easily readable way to write the above code is: 
print "Size array is not empty\n" if @size;
print "The frequency is FREE!\n" if @size && $freq eq 'FREE';

or if you intend to have more than one statement executed in the ifs 
if (@size) {
  #statements
}
if (@size && $freq eq 'FREE') {
  #statements
}
