Why aren't Lanthanum and Actinium classified as lanthanides or actinides?

Ok since I took chemistry back in middle school, I'll tell you #1: Lanthanum and Actinium are the beginning elements of the Actinide and Lanthanide series, that's why the series is named after them #2: They are chemically arranged differently (Ex:The # of protons and neutrons and electrons) #3 If they were in the series, why would the series be named after them?
