This is probably related to the known bug explained in [1]:

* Retrieving the domains or ranges of a property do not return complete 
answers

Queries to retrieve the domains or ranges of a property are not guranteed to
return complete answers. Mostly the results contain only a variation of 
asserted domains/ranges. For example, domain/range of sub/super properties 
are propogated in the role hierarchy but their sub/super classes are not 
included in the results.


If not, can you tell specifically which range is missing for which property? Complete and minimal code to reproduce the results would make things much easier.

What is not working? An exception occurs or missing results? Again 
complete and minimal code that shows the problem would help. With code 
fragments like this it is very hard for us to figure out what is going 
on and what is the expected beahvior.
