Hi Mr. ZHU
Thanks for the suggestion.
I have verified that there is no changes in Filter or Batch Name before and after the lines disappear.
Yes this page has a few customizations that i noticed while looking into your suggestion but they are not related to hiding or displaying information.
I also tested it on a trial version of BC without any customizations but it still behaves the same.
Also I'm currently using BC19.5 while facing this issue. How is it working fine for you? Can you please share your experience.
