Need to fix the Responsive View of the Mission Page's Filter and Clear Buttons.

The "Filter" and "Clear" buttons should always be visible no matter size of the browser's window. They are both visible if the window is at least 1731 pixels wide.

If the window is less than 1714 pixels wide the Clear button disappears and the Filter button becomes wider.

If the window is narrowed to be less than 1648 pixels then both the Filer and Clear buttons disappear

The .col-md selector is used by Bootstrap's grid system: https://getbootstrap.com/docs/5.0/layout/grid/#grid-options
