Hi, I’m using NestedHeaders.
There’s a problem with this feature after filtering is used.
Fiddle: https://jsfiddle.net/k4bx1asv/4/
To see the issue, just set filter for any column to “Is empty”. After pressing OK, there’s no data shown (and that’s correct).
The issue is that I can’t change the filter anymore (clicking on the “arrow button” does nothing).
