the fact that it happened on mine and it jsut doesn't "reload" data is very concerning. AMP dude was just like log off and on ..AMP never really cares about platform issues, it's not really their problem anyway
I once had a similar issue and someone told me how to fix it.
Click on chart-->properties-->colors-->line chart: turn the color into same as your other chart bar color. The problem is when line chart color is same as background color, you will not be able to see line chart bar.So there is missing bar.
But I am not sure if yours is the same issue as mine.
