Kostelano, спасибо.
1. Да поправлю. Я как то не думал, что это воспринимается дублем

2. Дубли типа .html появились благодаря вот этой включенной опции "Добавлять суффикс к URL = ДА"
Читал, что ее желательно включать, но получается стало хуже. И выключать теперь ее стремно, т.к. много ссылок именно с HTML. Так что странницы с суффиксом теперь главные.
Сайт я только набиваю статьями, предполагалось, что в каждой категории будет несколько материалов. Поэтому сделал категорию для каждой страны.
и все таки не понятно откуда растут ноги от этого -amigotripru

Если это не категория, то как оно генерится может?
Сейчас у меня .htacess вот такой:

update
Похоже ноги растут отсюда, т.е категория без категории была переименована когда-то, но потом вернул все обратно, как же теперь избавится? :
