Changes have apparently been made to the “Benefits and Payments” annex to the invoice which have the effect that
  1. the “descriptions” in the benefit items are presented as standard
  2. When the descriptions are displayed, a description that has been entered once in an expenditure item of the type hours in the contract structure appears again in all sub-items.
About 1: Not a bug, but it would be easier to understand if there were a notice when there were changes in existing billing processes.
On 2nd: apparently a bug. See screenshot below as an example.
