Repeat within Nested Repeat..?

Driving me mad for an entire day!

Nesting a Repeat is working fine but would like to display a third set of results within the Nested Repeat:

So for example lets say we have the following as a report:

User
Projects
Documents

User unique id being the filter at the parent level.

I’d like to display a report like such:

User/Details
Projects/All their respective Projects
Documents/Details.

Then Repeat the next User with the same…

I can get the initial Nested Repeat to display, Users/projects correctly following the Docs examples, but the Documents won’t display correctly inside of the Projects Repeat… Am I missing something plain and simple? Any advice truly appreciated!

Thanks in advance for assistance.
