Previously, spent hours where not shown at the description on the todo invoice. As the owner you want to know what has been invoiced to you so you don't have to ask any questions about it.
For that reason we have added, as a specification of the hours, the description of the todo to the invoice line.
** Note ** Tasks are currently not created multilingual. If you need to submit a todo invoice to an owner with a foreign language, you will have to manually edit the description manually.
