Good afternoon, I'm experiencing an error with my interactive report. When selecting three or more columns to group columns, when trying to remove them, it causes an unmapped error. All columns are collapsed into a single field, and it's no longer possible to remove this filter. To return the grid to normal, we need to use the restore function (Action → Report → Restore). I'm working with a 24.2 APEX version
First step add 3 columns to group:

I have to remove one of the columns (Código):

To return to normal, I need to reset the grid:

I tried to create simple queries with just one table, but it also causes this error. It doesn't matter what order the columns are removed (first, middle, or last), if there are more than three or more columns, it causes this error.
