Whenever we try to personalize a grid with an additional field, the field itself remains in the grid but the correct column is not kept. After reopening the Client the newly added filed is always in the first column.
If we do the same with several additional fields, the new fields can be sorted within themselves but they cannot be mixed with the "basic" grid fields.
It ends up with a group of additional fields on the left side of the grid and a group of standard fields on the right side of the grid.
This behaviour happens only with newly added fileds. Standrd fields can be moved and they remain where expected.
