Master language is always the language you first create the page in.
So you mean i created that page before Master Language was other one?
No. Master language is not a setting. It's just the first language any content is created in. E.g. if I create a page in swedish, then swedish is the master language no matter what master language other pages have. I.e. a webiste usually have multiple master languages.
We set Master Language for Website and all the pages inherit from Root but unfortunely some pages are taking other language to be their master Language.
Master Language : "en"
Selected Languages : en-GB > en > ..
I want to give some pictures but sadly Forum doesn't show them for some reason..
