Hmm, the posted JPG seems to be broken.
But here's a place to look: in the puppet panel, with no layers selected, you should see the Face behavior in the properties panel. Twirl down the "Handles" group to see which face parts it found. Is it showing the layers you expect it to find? (The tool tips will tell you what it's looking for.) Also twirl down Replacements to see the blink layers. Note that if it doesn't find a Blink layer for a given eye, it will scale the eye as you close your eye rather than switch to the replacement blink artwork.
Thank you very much. The left eye was indeed invisible in the 'Replacement' group. Then I saw I misspelled the blink layer. There was one 't' in 'Left' to much. After correcting it worked as expected. Thanks a lot.
