How do you format the SLA that is displayed on the eazyBI report?

Hello eazyBI community
In my report I would like to format the SLA which is displayed with the time I would like to display only the time for example ( 5m 23s ) instead of having ( TTS Yogi Vida:5m 23s )
To specify that I tried to format the measure but it does not pass

Need a quick answer please.
