How to set up and manage repeating events in Apple Calendar?

Dear Apple Support,

I’ve noticed an issue with the repeating event settings in the Calendar app. When setting an event to repeat “daily” and “every ten days” simultaneously, the event repeats every day, making the “every ten days” option redundant, as it could cause the event to repeat twice after ten days. These options should be mutually exclusive: either “daily” (or weekly, etc.) or “every ten days” (or other intervals), but not both together. Please clarify or address this in a future update.

Original Title: Calendar > Event Settings > (for example) Daily & Every 10 days” — is not relevant
