Tooltip going beyond screen on mobile with WordPress Shortcodes Plugin

Hi, I have configured 3 tooltips for a navigation bar and 2 of them work perfectly, while the third one is going beyond the screen on mobiles. I can see that the “left” parameter goes negative then and this parameter comes from the element itself (no additional css formatting). I have this plugin in staging so far, so I cannot give you a link as the live website does not have this functionality, but I paste below the website code for this tooltip:

<div id="qtip-2" class="qtip qtip-default su-qtip qtip-dark su-qtip-size-default qtip-focus qtip-pos-tr" tracking="false" role="alert" aria-live="polite" aria-atomic="false" aria-describedby="qtip-2-content" aria-hidden="false" data-qtip-id="2" style="z-index: 15003; top: 146.725px; left: -18.2px; opacity: 1; display: block;">

Do you know how to resolve this issue?

Many thanks in advance for your help!
