There seems to be a bug in the 1.5 beta web charts.
It's as follows:
I save a chart layout with more than 1 scrip (2 or 3 chart layout) and I then select another saved chart layout.
The glitch surfaces when I then reselect the first chart layout which was saved with more than 1 scrips. This time same scrips load in both the charts even though I saved different scrips in that 2 chart layout.
This is happening with 2 or more chart layouts with different scrips. Same scrip appears in 1 or more charts after that layout is reselected after going to a different saved layout.
For reference, I have come across this glitch with both Brave & Safari browsers running in incognito/private modes and have not tested it in normal browsing.
