This thread is resolved. Here is a description of the problem and solution.
Problem: I can't connect the homepage with it's translation using "This is a translation of" option
Solution: The cause of the issue was that it seems you started to translate (clicked in the plus (+) symbol) the Homepage in English US to English GB. When this happens a page is already created and/or reserved for this translation, that's the reason why you can't connect the GB translation to the US page.
I 'finished' the translation of the Homepage in US to GB and I titled it 'Home to delete', please follow this steps in order to solve the issue: - Go to Pages -> Pages in English GB -> Delete the 'Home to delete' page -> Remove it from the trash too -> Try to connect the Home in GB you created to the Home in US.
