Issue with iPhone Connecting to the Wrong Wi-Fi Network

Whenever I try to connect to a new Wi-Fi network, I select the one I want, and I'm prompted to enter a password. However, instead of showing the password prompt for the selected network, my iPhone opens the password prompt for a different network—"CDWiFi"—instead. I then have to manually cancel it, go back to the Wi-Fi menu, and reselect the correct network to get the right password prompt.

The most frustrating part is that "CDWiFi" keeps overriding my selection, and I often end up unknowingly entering the password for the wrong network. I can't remove "CDWiFi" from the list, and even after resetting my network settings, it's still there.

The only solution I can think of is a full factory reset, but that seems excessive. Has anyone else experienced this, or does anyone know a way to fix it?
