Alias is not working in Table Panel

OS: Centos 7
Grafana: 7.1.5
Installed via tar.gz file


Alias is not working without Date Histogram
If i dont set Date Histogram, Alias is not working

But if i set Date Histogram, alias worked?

So what happen?
I try to join/merge beetween 2 query in to single table with field “org.L”, but two query have same field “Count” (alias is not worling) so join/merge transformations is wrong. It show two column (org.L, count) instead of (org.L, Total A, Total B)
