Spirit Theme: Buttons Have Changed on Desktop View Only & Do Not Change Back

Hi Support,

I am working on a site that apparently went through an update but now I can't figure out how to get the buttons to appear as they did before.

The following problem is only occuring when viewing the site on a desktop, it is not appearing on the tablet or mobile views.

The buttons are normally white with a dashed outline in pink and pink font. They now show as white background with a solid black boarder.

I have tried changing the buttons to another button type I have also tried creating a new button style and still nothing. Can you take a look at this and let me know what might be the issue?

Thanks!
Martiel
