django url name lookup

I have three url pattern match to the same url name 

url(r'^report/newreport/(?P<number>\w+)/$', 'report.views.newreport',name='report_newreport'),  
url(r'^report/newreport/(?P<number>\w+)/(?P<edit>\w+)/$', 'report.views.newreport',name='report_newreport'),        
url(r'^report/newreport/$', 'report.views.newreport',name='report_newreport'),

When I tried to use 'url' to get full url like this 

<td><a href='{% url report_newreport report.applicationnumber %} ' target='_blank' >{{task.applicationnumber}}</a> <br/>

I got an error 

Caught NoReverseMatch while rendering: Reverse for 'report_newreport' with arguments '('',)' and keyword arguments '{}' not found.

Is that because I matched three urls to one url name? I think this shoudl be fixed by matching these three patterns to three different url names. Is that other way I can fix this error

Thanks

I think the issue is with the fact that report.applicationnumber is not generating a value: with arguments '('',)' in the error message indicates that report.applicationnumber's value is empty in which case the url tag attempts to match the URL pattern ^report/newreport//$ which does not exist in your URL list.
