I think the area=yes might be the problem. That would presumably put 
this information into the mapnik polygon table, but the rendering rules 
for admin boundaries seem to only be defined for ways.

Osmarender presumably just ignores that and renders it anyway.

To indicate the area, they can be put together again as multipolygon

Here are some examples of tagging of one of the German admin_level=4 


Regarding the admin_level question, I would think admin_level=4 for 
districts wouldn't be consistent with most other uses of admin_level=4 I 
know, as those tend to correspond to states (and treated as such by the 
renderers) The admin classification as far as I know was set up to be 
level=2 : country, level=4: state, level=6: sub state (district?), 
level=8: ...
The main categories tend to jump in 2s to give some room for categories 
that don't exist everywhere in the world, but still allow a more or less 
consistent tagging through out the world.
