T206 Minor League per T206 Resource

[toledo_mudhen]

Trying to determine how many cards make up the subset of T206 Minor League Cards.

When I select the listing for "Minor League" in T206 Resource it shows that subset as consisting of 134 Cards.

However, approximately 50 of those 134 cards listed are designated as "Southern" League.

So are the Southern League cards also part of the Minor League Subset or do they stand alone as their own subset?

Thanks for any clarification you can provide.
