Transparent buttons

Hey wtechgr,
Thank you for the link to your site, the transpercey is caused by this css:

body:not(.masterstudy-theme) input[type=submit]:not(:hover):not(:active):not(.has-background) {
    background: 0 0;
}

from: /wp-content/uploads/stm_lms_styles/stm_lms.css
to override this please try this code in the General Styling ▸ Quick CSS field or in the WordPress ▸ Customize ▸ Additional CSS field:

#top #main .main_color input[type='submit'] {
	background-color: #259dd9;
}
#top #footer.footer_color input[type='submit']{
	background-color: #fff;
}

After applying the css, please clear your browser cache and check.

Best regards,
Mike
