The bullet chart visualisation by Microsoft version no 18.104.22.168 was working fine till 6th August 2018. But it has stopped working now, We are unable to change the colours or enter any value in the maximum, satisfactory tabs.
Please look into it.
@mayankjn22,What is your Power BI Desktop version? I am unable to reproduce your issue in the Power BI Desktop July release.Regards,Lydia
