ATMS data assimilation, but num_tovs_global and num_tovs_local were not detected in any of the four files.

[fzl]

Four files were tried 00/06/12/18 and the assimilation time window was 6h. but still no local data could be detected。

For 00T, the rsl* file display reads as follows：
Reading radiance 1b data from atms.bufr
Bufr file date is 2020 4 1 0
atms
The number of observations is: 799998

For 06T, the same result：

Attached is my setup and the rsl* files.
Looking forward to help, thanks!
