Please note that in the metadata form there are funding fields at the bottom of each author block as well as a general funding field at the very bottom of the form (see "Additional Metadata").
In the PDF, all of these funding fields are merged to one funding block on the title page, where the author-specific funding fields are automatically preceded by the author's name.
Important! Please do not double funding information by repeating in the general field what is already contained in the author specific ones and vice versa.
As general rule of how to distribute funding information on the different fields consider the following: If a funding is clearly assigned to an author, please use the author-specific funding block. You should only deviate from this rule if the funding block on the title page of the PDF becomes unnecessarily long due to the fact that several authors have the same funding information.
