Redmine Table Calculation

The calculable fields are selectable in a multiple choice field. The choice in this field are grouped by tables. It is possible that a certain field was assigned to serveral tables. Hence, it is displayed below each table in the choice list.

After an administrator has selected the required fields and has saved her selection the selection seems to have changed. This might happen when a field was selected which belongs to several tables. Then each group (table) in the choice set has this field selected.

Moreover, the mulitple selected field has impact w.r.t. to the list of fields on the calculation index page and finally in the caclulation itself happening in a spreadsheet.
