They've tried to be clever and re-sort the location listing, but fucked it up badly. I suspect the ordering has been done by foreigners who've no clue of UK geography.
Essentially in most cases the problem seems to be the geographical hierarchy has been changed to remove cities and big towns
For instance previously to get Leicester it was ordered
Leicestershire>Leicester>area of Leicester
now it's ordered
Leicestershire>LE*-Leicester (* is post code number) with no regional area
they have introduced
Leicestershire>"City of Leicester" as a new term, but that does not pick up the whole city, which needs multiple searches for LE1, LE2, LE3, etc
It's bolloxed completely, but worse in some areas than others
