notification show query value

When sending a notification, we get the text as expected: 💔 ALERT Rule: CPU Usage | [DOCKERv2] CPU usage has been over 80% for more than 1min but we also have the query values!:

[ var='A' labels={instance=DOCKERv2} value=100 ],
[ var='C' labels={instance=DOCKERv2} value=1 ]

Is it the expected behaviour or shoud we just have the text and not the query values? Is there a way to disable it to have only the text?
