Issue with login form and application form in the same page

Hi,

In the mentioned page I have 2 forms. On left the login form and on right a simple application form.

But when I fill up the application form I see the following message for the login form:

Note: You are already attempting login using a different login form on this page. To keep your logging experience simple and secure, this login form in no longer accessible. Please continue the login process using the form with which you attempted login before the page refresh.

How can it be fixed? I need both the forms in the same page. The application form doesn’t create any user in the backend. It’s just a simple form.

Thank you.

The page I need help with: [log in to see the link]
