CFAI text versus Schweser:

I’m trying to figure out how Schewser’s LOS corresponds to CFAI LOS….

For example, In Schewser FRA Page 72 it reads “LOS 25.i: Convert income statements to common-size income statements” it says the same things in CFAI FRA page 149 in the intro…. but in the body on page 194 its under part ‘7 Common size analysis of the income statement’…. do the letters not show up in the body of CFAI readings, I thought the titles and headers of CFAI and Schweser were identical?
