Browser language detection for Greek

Hello,

I use the 2.6.7 polylang plugin verstion. I don’t use any cashing plugin.
I have English and Greek languages and the default language is set to Greek. The order is 0 for Greek and 1 for English. In “Languages”–>”Settings” i have disable the “Detect browser language” option.

However when i open the home page, the English version loads instead of Greek.
Note tha the full name of the Greek language have been set in Greek instead of English.

How can i fix it?
