ISSUE SUMMARY: Inserting paragraphs, bullet points or numbered lists works within the event editor. But, they are not displayed in the final event description. All paragraphs change to one.

So i tried to follow your instructions in support events page:
Instructions: put this CSS at:
/templates/socialize/css/custom.css
.joms-list__row ul {
list-style: inside none disc;
padding-left: 17px;
}
.joms-calendar__event-item ul {
list-style: outside none disc;
padding-left: 25px;
}


The problem is that there is no "socialize" folder in "templates" folder. Only "beez3", "jf_social", "protostar", and "system" folders. So i opened "jf_social/css/jf_custom.css" and pasted the code. But nothing changed. I edit the event and put paragraphs again in an event description but no paragraphs in event display.

Hi,

You can add this code for fixing this :

div#joms-event--details ul > li > ul {
    list-style: initial;
    margin-left: 26px;
}

Finally I solved the problem when I modified "Jomsocial Configuration > Layout Allow HTML Codes" from "no" to "yes"
