Kde battery indicator remaining time stucked

I have the latest kubuntu 19.10 with kde 5.16.5.
When I look the battery icon it show me the same reamining time no matter what is the percentage of energy remaining in the battery.
I monitor dbus with this command "dbus-monitor --system sender=org.freedesktop.UPower"
And I get this:

dbus-monitor --system sender=org.freedesktop.UPower
dbus-monitor: unable to enable new-style monitoring: org.freedesktop.DBus.Error.AccessDenied: "Rejected send message, 1 matched rules; type="method_call", sender=":1.1599" (uid=1000 pid=12348 comm="dbus-monitor --system sender=org.freedesktop.UPowe" label="unconfined") interface="org.freedesktop.DBus.Monitoring" member="BecomeMonitor" error name="(unset)" requested_reply="0" destination="org.freedesktop.DBus" (bus)".

So it seems that is receiving the good values but the battery indicator in the systray is not working at all. The only good value it gets is the total percentage of the battery.
