The following capture2 call works for me. 
my ($stdout, $stderr) = $ssh->capture2(echo => -n => '00 , 99.')

It doesn't seem to be have any problem handling output starting by 00.

Also, as you are not posting the full script, it is difficult to know if the issue may be originating somewhere else.

Try including the following code just after the capture2 method call and posting here its output: 

use Data::Dumper;
print Dumper([$cmd, $edr, $stderr, $?, $ssh->error]);
