Due to some bugs Google Translate option appears twice in some Confluence space.
Example
In order to make it corrected to have a single translation option as a normal behavior please follow the below steps
Step 1: Go to Space Tools→Look & Feel option
Step 2: Under Layout option, choose Page Layout and click on Edit
Step 3: There is ID called google_translate element which is called in CSS class here.
Usually we should have only one google translate element, but here we can see we have two elements
Step 4: Here we need to remove this entire Script tag which has the extra google translate element and save it
Step 5: And now the google translate option appears only once.
