In the CBS version, in paragraph 1 the abbreviation "1st" has no space after the "1" but the "st" did not jump to superscript as it should in MS Word. In your recreation, it appears you have put a space after the "1" which is why your "st" doesn't jump either.
Somewhat the opposite problem with the "147th" in paragraph 2. The CBS version has no jump to superscript for the "th" but there seems to be a space after the "7" so you wouldn't expect a jump. In yours, however, you clearly have no space after the "7", yet the "th" didn't jump.
Comments?
fyi...
Its not a number 1, its the letter l.
