I found this in one of the old posts on the site. Fixed the issue. Pls apply the following Css to the customer.css file.

body.ltr .sp-megamenu-parent > li.sp-has-child > a:after, body.ltr .sp-megamenu-parent > li.sp-has-child > span:after {
/*font-family: "FontAwesome";
content: "\f107";*/
float: initial;
margin-left: 7px;
}
