Solved Clearing Scoreboard Scores

Hey!
So I want to be able to edit a ScoreBoard displayed on the sidebar without any flickering
I currently have an Objective to which I just add scores with the stuff I need to be displayed like so:

Spoiler: Code

Code (Text):

private void setEntries(Player p) {
        List<String> entries = plugin.getConfig().getStringList("ScoreboardEntries");
        int i = 0;
        for (String entry : entries) {

            Economy econ = plugin.economy;
            entry = entry.replace("{Rang}", plugin.luckApi.getRang(p)).replace("{Money}", Double.toString(econ.getBalance(p)));
            //System.out.print(entry);

            objective.getScore(Color(entry)).setScore(i);
            i--;
        }
    }

Spoiler: Objective is created like so

Code (Text):

boardName = plugin.getConfig().getString("Boardname");
            objective = sb.getObjective(Color(boardName)) == null ? sb.registerNewObjective(Color(boardName), "dummy") : sb.getObjective(Color(boardName));
            objective.setDisplaySlot(DisplaySlot.SIDEBAR);

When I update the scoreboard with new Information (so for example let's say his group changed) it just gets added with the same score (which makes sense because I didn't remove the old one).
So how would I remove all the old scores to set them again?
I already tried the following:

Spoiler: Tried stuff

Code (Text):

//Makes it flicker

//        objective.unregister();
//        objective = sb.registerNewObjective(Color(boardName), "dummy");
//        objective.setDisplaySlot(DisplaySlot.SIDEBAR);
     
// Throws UnsupportedOperationException

//Set<Score> scores = sb.getScores(p);
        //sb.getScores(p).removeAll(scores);

 //Nothing happens

        //sb.resetScores(p);
        //sb.resetScores(boardName);
        //sb.resetScores(objective.getName());

 

Whoops, guess I didn't find that, thanks a lot
