Thank you! The new dialog looks excellent, it would have prevented my error.

Maybe it would also be sensible to not allow mass-edits to be triggered by past events. While it may be useful to tweak a single past event, I don't see much of a use case of updating all events starting from some past date. I'd argue that that is nearly always unintended.

Thanks @epriestley for the reply. Seems like my mental model of "prototypes" along with the misleading wording of "future" threw me off.

Hi @epriestley, thank you for your explanation.
