If you want to remove that information you need to remove ('.$counter.')
from functions wpestate_get_category_select_list , wpestate_get_action_select_list,wpestate_get_city_select_list,wpestate_get_area_select_list and wpestate_get_status_select_list from
wprentals/libs/help_functions.php file.
To remove it for subcategories you need to do the same thing but for function wpestate_hierarchical_category_childen .
For half map, search type 3 and 4 must make the same change on
wprentals\libs\search_functions3.php and
wprentals\libs\search_functions4.php
