Global keywords not appearing, only article keywords. - Joomla! Forum - community, help and support

i had site setup global keywords main keywords of site , article keywords extras specific page.
as long remember, system combined 2 when viewed "articles > article" pages..

eg.
global keywords: painting, art, artist, pictures, images,
article keywords: download, training materials, videos, tutorials
generated page keywords: painting, art, artist, pictures, images, download, training materials, videos, tutorials

this evening happened notice global keywords no longer appearing on articles.. article specific keywords! site pages reading "download, training materials, videos, tutorials" , none of main site content keywords!
i may have edited without realising it, setting active in global config..

i fix adding in keywords individual pages workaround , take forever (plus might cause duplicates if decides work..)

what file adds global keywords info pages?.. have no idea start looking! advice or general directions appreciated!

i think global displayed when articles keywords missing.
if have article kws these words appears on page source.
if have 5 articles own keywords display these , if have 3 articles without own keywords the global keywords appears , have 3 pages same keywords (global ones).
you have write on every article unique keywords (best seo thing, think keywords no longer means much).
