How can I get Siri to stop confirming a number I call several times a day??

I am using iOS 14.something. In the last few days, Siri has started asking, "Just to confirm..." before dialing a number I voice-dial several times a day! It is the only contact on my phone with this name. Is there some way to turn this feature off? Or can I edit the contact in some way so Siri will recognize the name on the first attempt??

Related: I visited https://www.apple.com/feedback/ to explain my issue. There is no link to comment on the iOS, only hardware, apps, devices, website issues, etc. In fact, you can't even select the iOS as a topic of discussion in this community! Wow. I am beyond frustrated.
