Hm, I'm not quite sure if you are asking another question here ... ;-)
But I assume you do.

However, without knowledge about the structure of Hecke or m,
respectively, in particular about their row numbers, it is impossible
to spot the cause of your "problem". I suggest you check the structure
of m:

str(m)

I suspect you'll see that the assumption of 52 trapcatch values is
somehow wrong.
