Here is what I could figure out:

Interviewer 803 only did men's interviews and is almost certainly a man. This looks like a coding error for the interviewer's sex.

Interviewer 920 is a supervisor code, and it appears that the person using the code at the beginning of the survey was female, but left the interviewing teams. The replacement supervisor was male and was originally interviewer 903 in a different team. 903 worked as a male interview in July and the beginning of August, but then was supervisor (using code 920) but was also conducted some men's interviews. This is not what should have happened. It can be corrected by recoding interviewer code 920 in the men's data as code 903.

Interviewers 201 and 207 are not clear. I think that there was probably some confusion in the team in terms of interviewer numbers and for a couple of clusters each a female interviewer used a male interviewer's number.

It is definitely possible that v028 and mv028 may be incorrect. Interviewers starting data collection in the cluster first provide the team number, then from within a list for the team they select their interviewer number. It is almost impossible for them to get the team number wrong as many things would fail, but it is definitely possible for them to confuse interviewer numbers, and we see a smattering of other cases that appear to be that type of problem. For 201 and 207 it appears that these were used incorrectly for two clusters each. It is possible that a couple of temporary interviewers were given the codes 201 and 207. I'm guessing for these two.

I might just mention that historically a few surveys have permitted men to interview women and women to interview men. For example the first Ghana DHS in 1988 permitted that as it was standard practice for their surveys at the time.
