Attempting to change regions in the dashboard does not display correctly

After logging in to the dashboard in one region I attempted to change regions by selecting the other region in the top right corner. After doing this, login credentials form elements appear on the bottom left-hand side and does not look correct (I have attached screenshots to illustrate what I see).

While I am not a UX expert, I do not believe that it is intended to display this way. I have tested in both Firefox and Chromium and experienced the same thing.

How to reproduce (see attached images):

 1. Login to the dashboard, selecting any one of the regions (image 01).
 2. Select a region from the dropdown in the top right corner and click on the region name (image 02).
 3. Notice the form elements appear in the bottom left corner (image 03).
 4. (And again) Scroll to the top of the page, select a region from the dropdown in the top right corner again and notice additional form elements appear (image 04).

What I expect (suggestion):

I expect the form elements to display "correctly". Perhaps as a rendered login dialog overlayed on the current page?
