Currently it’s set as English but I also speak other languages and I want to show this on my profile. For some reason when I try to add one more language, the language box stays red and the “add” button is greyed out.
I suggest you open a ticket with Customer Support. Explain your situation with screenshots and what not.
I doubt anyone on the Forum can help with this issue.
I tried to add a language on my end. The first time, I typed in “Spani” and thought the auto-complete had filled it out, but the add option was greyed out. I tried again, and would have been able to complete the process (but my Spanish is not so good).
