Unable to browse DFSR shares / namespace

Hello

I have an interesting situation that I am trying to get to the bottom of

I have a DFSR namespace setup - and several folder targets configured as part of that namespace. Lets call this\\contoso\dfs\shares

I have two accounts, my standard domain user account, and an administrative account

If I Browse to the DFSR share via my admin account - I can see all shares

\\contoso\dfs\shares\
 - Data 1
 - Data 2
 - Data 3
 - Data 4

If I browse to the DFSR share via my user account - I can only see two of the 4 shares

\\contoso\dfs\shares\
 - Data 1
 - Data 4

If I browse to the share directly using my user account - it works fine

\\contoso\dfs\shares\data 3

 - Some files

I have confirmed that my user account has the following effective permissions on\\contoso\dfs\shares\

Traverse folder / execute file
list folder / read data
Read Extended attributes
Read permissions

I have confirmed that my user account has the same effective permissions on Data 1 / Data 2 / Data 3 and Data 4 subfolders

Traverse folder / execute file
list folder / read data
Read Extended attributes
Read permissions

I don't understand what is stopping my user account from seeing the missing folders from the namespace, when the permissions are the same. The folder targets are not hidden shares

The folder targets are on different servers. I have checked the folder targets on each server and the permissions are set the same

I can confirm that if I browse to \\constoso\dfs\shares and\\contoso.microsoft.com\dfs\shares via my user account that the result is the same

Any assistance in relation to this would be appreciated
