How to update the teams I'm managing in the career section

Hi all,

I have a career on this Forum and I started unemployed. Now that I got hired I wanted to update the team and league I'm managing in but everytime I try to insert the team or the nation I'm managing in it just goes back to blank and doesn't let me add anything.

It's my first time posting a career so I'm sorry if the fault is mine. 

Thank you
