1. If your toes look like this (you can see more than one set of nails and you can see the applier polish) redeliver your eBODY and start with a new copy.
2. If your toes look like this (you can see more than one set of nails with white or only alpha showing) then it is a masking or graphics issue.
Turn off the unmask button and it will fix along with any white body problems, especially under water.
3. If #2 does not work or if you have the 1L version then it must be solved with graphics settings. Follow the directions for graphics preferences here.
