BAFA application, correct wrong house number?

Hello, we submitted an application for funding measures for the use of renewable energies in the heat market in December 2020 (heat pump in a new building), which was also approved, even extended once in the meantime, and now the proof of use is ready to be uploaded. In this context, we noticed that at the time of the application everything was entered correctly, except for the house number under: "Information about the location of the measure, if different", which is just one house number off. This was because the property could not yet be purchased notarized at that time, and the house number was therefore only assigned after the building permit was submitted. Can the house number still be corrected? Is it sufficient to add it when uploading the proof of use? We hope that this circumstance will not invalidate the application and that we would thus lose the entire grant. As described, everything fits, including the street, just not the house number. Has anyone had experience with this? Thank you all.
