Objects appearing in unwanted charts

[Keith Gwemende]

After plotting my trendlines and other objects on the MT5 platform on windows on a certain chart e.g V50 1s I am finding these objects present in unwanted charts such as the V75 making my charts a bit untidy and when I attempt to delete these objects on the unwanted charts i.e V75 I find all my work done on the V50 1s completely removed as well. SO how can I make sure my objects do not appear on different charts or is it a bug in the program ? I have attached screenshots of said examples below.
