Looking at the original census form for the Jester family they are directly beneath 164 - 165 Exclusive. The Jester family has 166 against their entry and the street name is at the top of the form so it could be that when the site transcribed from the census they assumed the Exclusive applied to 166 also?
That seems very likely Suzanne, especially as it looks like 166 are one side of the Schofiled st junction , and the other two, or at least 164 , are the other side. 164.165 are noy listed in any directory I have, but counting back from where other shops must be would seem to make it very likely / almost certain that 164 is the other side of the junction
