Tab section – full width

I have been having trouble with the tab section.
1. The titles of the tab section are centered and not full width. This just doesn’t look good to me.
2. If I add a title and text to one of the tabs, all the text is at the left. I added a 1/1 colum to see if that would change it, but still nothing.

What am I doing wrong?

I also added this to my css:
/* CSS – Tabs with equal space*/
.js_active .av-tab-section-tab-title-container {
display: flex!important;
justify-content: space-around;
}

Because before all the tab titles were centered in the middle.
