Objects doesn´t work properly

I place a trend line or a Fibonacci retracement on the chart, for example, and once they are placed on the screen, I can no longer select them to work on them, for example, if I want to extend the trend line or if I want to move the anchor points of the Fibonacci retracement tool a little higher or lower. They do not appear as selectable. The functioning of the objects on the screen is terrible today. They must fix it because it is the most basic thing that can be asked of a tool as prestigious as forextester and today it is a shame and does not live up to its fame.
