Sign Up Modal showing unnecessary buttons

[kuttumiah]

Observed problem

When I'm Clicking on the Sign Up button for the first time then I get two large buttons at the center of the modal.

But if I click anywhere in the window then the modal is closed. Then if I click he Sign Up button again then I get the previous modal again but this time with two more buttons added to the modal.

I also get the same two more buttons if I click one of the buttons in the Modal to sign up and go back to the Initial modal with the Back button.

When I get this two more button one is enabled (Back) and another is disabled (Sign Up). But the enabled Back button does nothing.

Expected result

1. When I'm Clicking on the Sign Up button for the first time then I get two large buttons at the center of the modal. I should get the same when I click the Sign Up button next time after closing the modal by clicking anywhere in the window.
2. If I click on any 2 large buttons of the modal and get inside then I should get the Back and Sign Up button. Which I'm getting currently. But if I get back to the main Modal again then the Back and Sign Up buttons should not be visible.

Steps to reproduce

1. Click Sign Up button at the top right corner of the Home Page.
2. Click anywhere in the window outside the Modal.
3. Then again click Sign Up button at the top right corner of the Home Page.
