If you have multiple cities with the same name but in different regions, in breadcrumbs you will see the same region for all the different cities.
Verified and issue happen when there is city in search but not region (to support canonical URL structure).
Fix require refactor of breadcrumbs and will use more effective methods.
It also require refactor of search variables stored into session to reduce number of DB calls and be more efficient.
Due to above, fix will be included in Osclass 8.3
