How do I permanently delete an event category from a Sharepoint site?

[ruthmof]

I'm building a SharePoint website with an event calendar. I deleted one of the categories from the calendar settings. Nevertheless, I cannot manage for it to disappear from the category drop-down list both in the events filter and "Add event" form, though no calendar widgets and no existing event entries have this category assigned:

However, it still shows!

Does anybody know how I can get rid of it? Thank you in advance!

Hello @ruthmof 

the category entry still exist, until there is no entry for this category. 

I have checked this and i can reproduced, after i delete all items with my deleted category, the the entry will disappear.

Check the categories in the allitems view, it's a default view with a good overview:

https://<TENANT>.sharepoint.com/sites/<SITE>/<LIST>/AllItems.aspx 

Best, Dave

Hi David, BINGO! From the "Allitems.aspx" view, which I was unaware of, I spotted one entry which still had this category. I've removed it and it's finally gone. Thank you!!!
