Following is a response from DHS Research & Data Analysis Director, Tom Pullum:

You are right--the 2013 survey has only 73 strata, and the two other surveys have 74. In the 2013 survey, Lagos does not have rural cases, whereas in the 2008 and 2018 surveys it DOES have rural cases. The stratification variable, hv023, consists of all combinations of shstate and hv025. (hv024 is the six major regions.) The labels for shstate are consistent across the surveys, but the numbering for hv023 is not consistent.

I don't know whether the absence of rural cases for Lagos in the 2013 survey was due to a temporary re-definition of Lagos as all urban or was due to something in the sample design. However, what you have done is fine and nothing in your construction of svyset needs to change..
