Tutorial 6 has a problem

[StevenMcgrew]

Hello,

Supposedly this issue in Tutorial 6 where the basenames are plural instead of singular was fixed as shown here pull 8517, but I was doing the tutorial today, and it is still plural and caused errors for me. It's kind of frustrating for newbies doing the tutorial, because we assume the documentation is right and that we are the ones who made a mistake somewhere. It takes a lot of time to find the solution to the problem for those of us not familiar with this framework. Please fix.

Thanks,
Steven McGrew
