Code splits a single session into several Matomo visits?

Hello. I am seeing some strange behavior in my site, which I recently moved to Matomo. It seems as if a single user (i.e. the same IP, computer, etc) has a visit, two pages are seein within seconds, and it is split to two visits in Matomo.

I asked Matomo's support, they say they cannot support this because its from the plugin. So I'm trying here...

Anyone else seeing this?

here's my code, seems to be fine, but maybe some error in the implementation?

var _paq = _paq || [];(function(){var u=(("https:" == document.location.protocol) ? "https://MYCLOUDADDRESS/" : "http://MYCLOUDADDRESS/");_paq.push(["setSiteId", "9"]);_paq.push(["setTrackerUrl", u+"matomo.php"]);_paq.push(["setDoNotTrack", 1]);if (!window.matomo_search_results_active) {_paq.push(["trackPageView"]);}_paq.push(["setIgnoreClasses", ["no-tracking","colorbox"]]);_paq.push(["enableLinkTracking"]);var d=document,g=d.createElement("script"),s=d.getElementsByTagName("script")[0];g.type="text/javascript";g.defer=true;g.async=true;g.src=u+"matomo.js";s.parentNode.insertBefore(g,s);})();
