after theme update to 27.4.4 / Buttons colour lssue fo all pages

After theme update to 27.4.4 / Buttons colour lssue fo all pages. How to fix this situation? This happened after the betheme update. At the moment as a temporary measure I import every time pre-saved settings for the whole theme, backup of which was made before betheme update, but if I change any settings inside the theme, the style of buttons or rather its background changes. Please help me to solve the problem. (radiyled.com)

To make it clearer, I attached screenshots. After the update, the theme automatically replaces the border-color parameter with background-color across the entire site. Manually fixing this for every button on every page isn’t an option—it would take way too much time. I also can’t use a single CSS rule since I’m using multiple border-color values for buttons
