Unreal Insights. infinity in timing

report
You can help. I’m trying to learn how to use Unreal Insights and here I stalkalkalkalka with the problem that in the graph of time I get an infinity sign. I’ve tried to take pictures before the game starts and after, but the result is always the same and the sign does not go away.
RenderDoc shows these values but it does not suit me.
Ctrl + Shift + , show only the current frame.
What does the infinity sign mean and how to remove it to get accurate information?
