Data table has exclamation triangle icon

when i user kibana to veiw data table, it has exclamation triangle icon.like this:
%E5%BE%AE%E4%BF%A1%E5%9B%BE%E7%89%87_20190711152755

What does it mean?

If you mouse over that exclamation triangle it should say what it means in the tooltip.
One of the more common ones is this: "Objects in arrays are not well supported", which would be the case for dissect.info, from what I can see.
