Button Style Problem

This plugin was a wonderful one, when I have worked on it, it was difficult to make things work as needed, but finally, I got everything working fine working with woocommerce.

One of the things is the button style, I got it as needed, but recently one of the products buy now button style changed for some reason, while they all have the same setting, so nothing specific for a single product.

Please review the linked image.

Any solution to fix this?

By the way, I tried to update to the latest version but it created more problems, so I had to go back to the older version.

Thanks,
