"Select Test" dialog in "Organize Tests" no longer lists new script files

All of a sudden, when I open up the "Select Test" dialog from "Organize Tests", newly added script files are no longer listed. I have tested deleting script files and recreating them, but the result is the same. If I remove an older script file which is listed in the "Select Test" dialog and then recreate the file using "Script > Add > New Item...", the script file and its methods are no longer listed.



I am using TestComplete Enterprise 7.20.
