Is there any way to stop auto save chart layout?

When opened saved chart layout in window1 and opened another window2 with another stock then second one will get automatically saved. How to avoid this?

I am drawing trendline on higher time frame like 15,3060M but when I changed timeframe it is not at all visible even i have selected trendline visibility setting for all time frame.

This is really annoying me. Any solution for this?
