"Suggest leaving it as "Site Language" then using the "Language Switcher" module to let users switch languages."
I did this and developed Menus for each of the below languages and tested them one by one with the "Language Switcher" :
English: Ok for GB NZ AU, and issues shown as stated earlier for US, CA
Spanish: light issues shown as stated earlier for Spain and no translation for CO
French: light issues shown as stated earlier CA and FR
Italian: light issues shown as stated earlier instead of translated language
Chinese: light issues shown as stated earlier plus English
Chinese Simplified: light issues shown as stated earlier plus English instead of translated language
Hindi: light issues shown as stated earlier plus English instead of translated language
German: light issues shown as stated earlier plus English for LI, LU, DE, CH and AT
Russian: light issues shown as stated earlier plus English instead of translated language
Arabic: light issues shown as stated earlier plus English instead of translated language
Portuguese: light issues shown as stated earlier plus English for BR and PO
Swahili: light issues shown as stated earlier plus English instead of translated language
Ukrainian: light issues shown as stated earlier plus English instead of translated language
Hebrew: light issues shown as stated earlier plus English instead of translated language
The params field still is not appearing with any of it choices and they are hidden.
The language that was displayed the results on my original message was a "English US".
Thank you
