The entry above for 44 Baker Street is two separate households. Can you see the line running under John Drummond, 18 yr old grandson. This indicates the end of that household.
I think the section below has become scrunched up missing off a couple of line. I think parents and Jane and or son Robert should be listed there. I think I can see the bottom writing for Robert under John Drummond.
If you look at Annie, John and Euphemia, they have 'Do' (ditto/the same as above)) written for their surname. Because there are lines missing (with Glen), the transcript is picking up Drummond from the John Drummond in the household above.
If you count the number of females and males on the page, there are some missing (the totals for the columns show at the bottom of the page).
Henry Glen and baby Margaret and over the page. Margaret quite rightly shows as granddaughter...to John Glen and Annie Stewart!
A bit of a mess but I do think the whole family are living there
