Thank you for the report.  However, that is not a bug.
The problem is that your input is not sorted, and comm
requires that each input stream be sorted.

Using the --check-order option shows the offending line:

    $ comm --check-order -1 -3 MNF.lst sketch.lst
    11250
    comm: file 2 is not in sorted order
    [Exit 1]

I've closed this "issue".
