utm grabber doesn’t work with cloudflare

Hi, my wordpress (elementor) site is hosted on siteground and I’m use the utmgrabber plugin. Once I enable cloudflare caching (cache level: standard) the utms are removed from the url when i visit it. See sample url https://www.gloww.us/webinar?utm_source=test&utm_medium=test&utm_content=test&utm_campaign=test
