OK, let's find out what it really looks like; you can run DBCC IND on the index in question:

dbcc ind ( { 'dbname' | dbid }, { 'objname' | objid }, { nonclustered indid | 1 | 0 | -1 | -2 } [, partition_number] )

There will be a row for every page in the index so you might not want to take your largest index.

Also, even though PAD_INDEX is depending on FILLFACTOR (and that doesn't seem to be set), check anyway:

SELECT object_name(object_id), index_id, fill_factor, is_padded

FROM sys.indexes

WHERE object_id = sometable

AND index_id = someindex
