[shwetamandavgane]

Steps to reproduce:

1. Navigate to "Maps" page
2. Click Advanced Search button
3. Enter "900" - "15000" in Population field.
4. Click Apply
5. The pop-up stays there instead of disappearing
6. Now, enter Seattle in search bar
7. The pop-up still stays there. See image below

Expected:
The pop up should disappear once Apply is clicked

Actual:
The pop-up is visible and the search results look clumsy
