Index not shown in "Enable Summary Index" dropdown

[Splunker8]

I've created a summary index and user with admin role can see it when selecting "Enable Summary Index" option but the but the user with power role cannot see that index at all.

Does the Power role have the new summary index in their list of indexes they are allowed to access?

Are you using a distributed environment?  If so, how was the index added and was it also added to the SH?
