Button shape change not working

I am trying to change the shape of the button on the following page:

What I want is for the button towards the bottom of the page (under the report image) to be the same shape as the button in the layer slider. I have changed the color, but the other commands are not taking. I have tried the following CSS code:

.avia-button { border-radius: 100px; !important; }
.avia-button.avia-size-xlarge { font-size: 28px; } /* for large buttons */
.avia-button.avia-size-large { font-size: 24px; } /* for large buttons */
.avia-button.avia-size-medium { font-size: 24px; } /* for medium buttons */
.avia-button.avia-size-small { font-size: 24px; } /* for small buttons */

I have also tried to edit the border radius in Enfold –> Advanced Styling

Nothing seems to be changing this shape!

Thank you!
