Values exist in the wp_options ‘permalink-manager-uris’ field that we can’t edit

We are using your Permalink Manager plug-in on our site. The site recently got migrated from a hosting company that owned a lot of licenses for more advanced versions of our plug-ins that we didn’t receive upon migrating to a new host. So the version of your plug-in that we are using is the free one. The issue we are having is that there are values in the database record used by your plug-in that we can’t seem to see or manage on our own through the plug-in’s admin interface. I have exported the wp_options value for ‘permalink-manager-uris’ here: https://www.xosoftware.com/files/permalink-manager-options.txt

These are the values we need to remove from the ‘permalink-manager-uris’ data:

Array
(
[19739] => news
[19740] => news
[19746] => news
[19747] => news
[19774] => news
[19775] => news
[20011] => news
[20336] => news
[20337] => news
[20349] => news
[20408] => news
[20414] => news
)

The data stored in the options field looks like this for these records:

i:19739;s:4:”news”;
i:19740;s:4:”news”;
etc.

so they all have the s:4 value associated with them.

Is it possible that we were using the Pro version of your plug-in and now that we have reverted to basic we can’t see these records anymore? I tried manually removing the from the ‘permalink-manager-uris’ value, but that ended up basically removing *all* of the permalinks we’ve set up, and we don’t want that.

If you could point us in a direction with this I’d appreciate it!
