Could you please confirm if you have also filled in the "Company" field at the top of the window, and have also selected "Account Manager" from the drop-down option/menu when you typed it in the "Title" field?
Please also confirm if the issue persists when you try to clear your cookies, or when using a different browser.
Yes, I have entered the company and title. Though, I have tried again now to enter the work experience and it worked 🙂
Thank you for your prompt response!
