I finally discovered a small typo in the specanoun.php script. "Expires" was shown as "Exirpes" or something.
$saData = array('false',$uts,'ADD TITLE','#99FFAA', '#222', 'Add message', '#DDD', 'black', '99%', 'center', 'center', 'Expires', 'OFF', '2', 'No');
Changing in this line was "necessary, but insufficient" as they say. I also had to edit the text in the drop down box under the DISPLAY EXPIRATION section. It was held in the sadata.php in the /sacache directory. After the fact, I can see that the sadata.php file updated after I made this entry, so it probably could have been corrected here as well.
Doing both things seems to have resolved it. It took me quite a while to even notice this. I have been using this script for quite some time.
