Well your seal looks to be there, as A Dab of Oppo says they do seem to weep a bit around the cap base & the warning lable is often damp with fluid on the master cyls on 4 wheel trads, don't over fill as when you submerge the float attached to the cap it raises the level of fluid quite a bit
Edit, just zoomed in on the photo & you can see the fluid just slightly up the neck of the internal filler tube...too much fluid in there matey !
