To speculate: probably because the preceding “2” increases the likelihood that a “1” will follow it instead of an “l” or “i” in Google’s algorithm. Though if that is the case, then I don’t know why it doesn’t assume that “January” is more likely to be followed by “11th” than “llth”.
Weird that the 21st doesn’t have the same issue.
