Probably because you cannot write to an RODC

'4' means 'The object is writeable on this directory.', well it isn't on
an RODC, so '0' is probably correct.

See above.

Replication is one way into the RODC

This may be a problem, but then again it might not be, to 'delete' you
have to have 'write', but you cannot write to an RODC.

Are you using the RODC's in the same site as your RWDC's ?
If so, why ?
RODC's are meant to be used where there are security and/or other
concerns, so if you have RWDC's at the same place, why use RODC's ?
