Unknown Bulletin/dot on Sidebar

I find there is a weird dot appearing in my site whenever i have sidebar for it. After a thorough check, it seems like the issue causing by hello elementor theme as I found a strange code of : : marker appearing by using inspect function in google chrome.

My site come WordPress version: 6.4.2, elementor version: 3.18.2, elementor pro version: 3.18.1 installed.

The code under inspect view is as screenshot at below. Any idea on how to get that dot removed?
