Hi @it12uw,

it looks like you are trying to report a bug. Normally it helps giving the version of Odoo you are using and at least the button you clicked.
This one unfortunately seems pretty obvious and also was reported on stackoverflow it seems.

It affects https://github.com/odoo/odoo/blob/16.0/addons/l10n_id_efaktur/views/account_move_views.xml#L44 at least up to 16.0. So technically you should report it in the @odoo issues https://github.com/odoo/odoo/issues and maybe ping the authors there. If you have an enterprise subscription you might wanna use the support flow there.

The workarround for this is to download the E-Faktur one by one. (Not a good workarround, i know)

Having said all this, this doesn't really seam to belong to the @OCA discussions.

regards
Andreas
