Summary Report and viewlist Fail with large table

I have a table with several fields, and I have noticed that if I enable enough fields to outfit the screen it closes like an accordion between the paging section items, and doesnt let me see any info.
If I disable some field to fit the screen, problem is gone.
What can be done?
Thanks.

You may test the following two settings:

  1. If you have enabled Fixed Header Extension for the report, try disable it.
  2. If you have enabled Tools → Use Bootstrap responsive tables, try disable it.

Thanks. It works now. Second option
2. If you have enabled Tools → Use Bootstrap responsive tables, try disable it.

Now I reenabled and works as expected.
