The problem is that you've created parking areas inside the
leisure=sports_centre area. Aside from whether it's a good idea to tag
*all* that area as a sports centre and not just the areas that people
actually play sports on (which presumably isn't on the parking lot)
here's how you fix it:

1. Download the multipoly plugin
2. Restart JOSM
3. Download and select everything in that area
4. Search for: selected type:way leisure=sports_centre | amenity=parking
5. Tools -> Create multipolygon

Now you've created a multipolygon which conveys that you'd like the
sports centre to have holes where parking lots are. For further info
see here:

You could also just add layer=1 to the parking lots, but that's lazy,
somewhat likely to break and doesn't correctly markup the data (the
parking lot isn't a sports centre).
