Custom CSS in settings do not apply anymore

Hi there,
As you can see in the link provided, the custom CSS one can provide in settings do not apply anymore. This is the custom CSS, I use in there for the tabs:

/*Tab, any state*/
.su-tabs > .su-tabs-nav > span {
border: 0px;
background-color: #ffffff;
color: #1e73be;
font-size: 16px;
}
/*Tab, on mouse over*/
.su-tabs > .su-tabs-nav > span:hover {
color: #dd3333;
}
/*Tab, active state*/
.su-tabs > .su-tabs-nav > span.su-tabs-current {
color: #202020;
}
/*Tab content*/
.su-tabs > .su-tabs-panes > div {
border: 0px;
background-color: #ffffff;
font-size: 16px;
}

For example, there should be no border but it has displayed a border since this morning.

These styles shall have higher priority compared to original styles of shortcodes? This is still valid?

I am a paid customer with full licence for Shortcode Ultimate.

Thanks for feedback / solution.

Cheers, Eric
