Hi, I'm getting the 2 following errors after adding points to a Road Spline( like 100 points using a script), this worked before, but now it's throwing an error and I can't use the Gena Spline editor 

GUI Error: You are pushing more GUIClips than you are popping. Make sure they are balanced.

Using Unity 2021.2.7F

Gena 3.3.14

        if (useGena)
        {
            int i = 0;

            GeNaNodes = new List<GeNaNode>();
            //  public GeNaSpline GenaRoad;
            //List<Transform> newMarkerPoints = new List<Transform>();

            newMarkerPoints.ForEach(newMarkerPoint =>
            {

                print("Add marker at " + newMarkerPoint.name);
                GeNaNodes.Add(GenaRoad.CreateNewNode(newMarkerPoint.position));

                if (GeNaNodes.Count > 1)
                {
                    //lastNode = currentNode;
                    GenaRoad.AddCurve(GeNaNodes[GeNaNodes.Count - 2], GeNaNodes.Last());

            });
