FNCGrid - CheckBox problem

I have exactly the problem described in the following thread:

Also when I explicit do (after filtering)

gMatrix.Columns[act].ColumnType := TTMSFNCGridColumnType.ctDefault;
gMatrix.Columns[act].ColumnType := TTMSFNCGridColumnType.ctCheckBox;

still some of the rows remain with text "TRUE" (all rows have value "TRUE") and some are showing checkbox "Checked". Only happens when filtering.

Is there a solution for this?

About the issue, please try adding checkboxes with AddCheckBoxColumn instead of setting the ColumnType. Please note that FNC Grid is in maintenance mode, consider changing to TTMSFNCDataGrid instead, where this is no issue.
