Hello,
The responsive text block is designed to make the text responsive (different font-size) for all types of devices. http://prntscr.com/oi0nbf That is why this block is destined for one tag only. It means that if you want one title, one text, and one more text, you need to use three Responsive blocks: one for the title, one for the text, and one for the next text.
In your case, you use a number of tags in your texts: titles, texts, you would better use the default text block of WP Bakery page builder. http://prntscr.com/oi0nim
