Symptoms
When copying a value from the "Add/Edit" line in a list view, to a data label, when adding an additional point in the value, the copied value looks strange. Example: 1.2 works fine, but if you enter 1.2.3 in the "Add/Edit" line copies some strange value to the data label... Value: 1041494400000
Diagnoses
This is a bug and the ticket was sent to LABS.
Resolution
As a workaround, we configured a rule on the "Add/Edit" textbox on the "number" textbox that transfers data to the data label.
