Hi Stefan,
The entry for finger is an image that does not have any spelling
information.
http://signbank.org/signpuddle1.6/canvas.php?ui=1&sgn=53&sid=3576
It can not be used in translation because it is only an image. This
entry is a left over from when SignPuddle used images. To use this
in translation, you'll need to recreate the sign with SignMaker and
then remove the image.
Regards,
-Steve
