Duplicate cash receipt pending post, won't let me post it

It looks like I have a duplicate receipt entry, one is type Csh rc and has posted correctly to at, however the other entry is type Cs cs rc.  Same date, same check number same amount.  The problem is the second type Cs cs rc is "pending post" so it will not let me delete it or adjust it.  I have posted everything but it still won't let me delete it.  Anyone else have this problem?
