Removing "bullets"

Hello,

i have been setting up my post display, successfully adding a line in between and aligning the image. but i have not been able to remove the Squares (or bullets as they are called?) in front of my posts, checked the posts around here and the github page, but without results.

if i understood correct adding wrapper=”divs” to my shortcode i should be able to edit it, but im not experienced with coding,

anyone know what to do ? many thanks!
