Menu Arrow Marker Editing

I like the arrow that appears on the main vertical menu when selected, but when you select a sub-menu, two arrows appear and cover text on the main body. How can I eliminate the second arrow? Thank you in advance for your time.

Hi
you should only have 1 arrow. Give me your url to check this
CEd

The url is:

elitecollegelink.com/index.php/component...c2VyJkl0ZW1pZD0xODQ=

Use guest for both the user and password to see the menu.

by my side there is no arrow in the menu, the green arrow that I see is on the article title ...
the menu is with the grey background on the left with + / - icons

When I click on one of the menu titles, it becomes active and it displays a green arrow to the right of it. If you select team, one arrow appears. However, if you select founder in the submenu, then two green arrows appear to the right of the selection.

ok I see
this arrow is defined into your template.css file
elitecollegelink.com/templates/protostar/css/template.css
line 7420 on
#sidebar li.active:after {
content: url("../images/arrow.png");
float: right;
margin: -32px 0 0 244px;
position: absolute;
}
