I used a merged file (superkit) and found my mtDNA?

I used DNAgenics to merge my MyHeritage and my AnceastryDNA kits. I know they don't contain mtDNA information, as far as I'm concerned, but since the new Superkit was in 23andme format, I decided to upload it to James Lick's mtHap utility, as it accepts 23andme files.

It gave me this result:

How is it possible that it finds markers, if they were not present in the original two files in the first place? Or they were, but the files weren't readable just on themselves?

Can anyone comment?
