Siri did something weird and disturbing

I said “Hey Siri, remind me to fix Kateva”. (Shorthand for fix

Siri created a reminder “Fix Kateva thunder desensitization”.

That isn’t a random error. I believe I had that as a task name in – years ago. Spotlight can’t find it on my iPhone now though. ToDo can’t find it either.

So where did Siri get that from?
