Multiple Polkit errors on OpenSUSE Tumbleweed make the network unusable

On login, or when NetworkManager is restarted, an error message from PolicyKit 1 pops up:
```
System policy prevents enabling or disabling device statistics
An application is attempting to perform an action that requires privileges. Authentication is required to perform this action.
Password for root: ____
OK | Cancel
```
Call this Message 1.

On attempting to turn Airplane Mode on/off, two more messages pop up in sequence.
```
System policy prevents enabling or disabling Wi-Fi devices
An application is attempting to perform an action that requires privileges. Authentication is required to perform this action.
Password for root: ____
OK | Cancel
```
```
System policy prevents enabling or disabling mobile broadband devices
An application is attempting to perform an action that requires privileges. Authentication is required to perform this action.
Password for root: ____
OK | Cancel
```
Call these Messages 2A and 2B.

On attempting to connect to Wi-Fi, another message pops up.
```
System policy prevents control of network connections
An application is attempting to perform an action that requires privileges. Authentication is required to perform this action.
Password for root: ____
OK | Cancel
```
Call this Message 3.

Nothing happens (visibly) when message 1 is cancelled.
When messages 2A and 2B are cancelled, airplane mode cannot be switched.
Message 3 appears after I enter the Wi-Fi password.
When message 3 is cancelled, Wi-Fi does not connect, and a notification appears.
```
Failed to add Network_SSID
Not authorized to control networking.
```

I have modified 2 files in /etc/polkit-1.

::: spoiler /etc/polkit-1/localauthority/50-local.d/10-allow-network-manager.pkla
```
[Network Manager all Users]
Identity=unix-user:*
Action=org.freedesktop.NetworkManager.*
ResultAny=no
ResultActive=yes
:::

::: spoiler /etc/polkit-1/rules.d/10-org.freedesktop.NetworkManager.rules
```
polkit.addRule(function(action,subject) {
if (action.id.indexOf("org.freedesktop.NetworkManager.") == 0 && subject.isInGroup("network")) {
return polkit.Result.YES;
}
});
```

My user is in the "network" group.

After making these modifications, messages 2A and 2B will still appear, but airplane mode will switch if they are cancelled. Messages 1 and 3 still appear.

I am on an Acer laptop, with OpenSUSE Tumbleweed and KDE.

What is the cause of this, and how can I fix it?
