Unable to delete a process group in Nifi.

[#1]

I have downloaded a processor group from a template and performed some operations. I wanted to delete it as i got fully established workflow in which the same processor group is present again. So, i don't need the previously downloaded processor group. When I tried to delete it by right clicking on it and select delete option, It is saying unable to delete it due to some controller services are not disabled. I checked everything and could not find any enabled controller service.
