Unable to discover Why No Join Predicate

Please help me, I have this query:

select pc.Val, 
       PC2.Valstring as valstring, 
       pc.ValString as MessageType, 
       pc2.Val as Port
from dbo.tblproperty            p with(nolock)
inner join dbo.tblpropertycfg  pc with(nolock) ON p.pkPropertyID = pc.fkPropertyID 
inner join dbo.tblpropertycfg pc2 with(nolock) ON p.pkPropertyID = pc2.fkPropertyID
where p.pkPropertyID  = 5
      and pc.Concept  = 'PBX'      
      and pc2.Concept = 'PBXIP'

I am attaching the Excution Plan, this plan showing "No Join Predicate" Warning, I am unable to discover  where is the problem, please help.
