Thank you very much for founded and reported bug. We have already fixed it; now you can use the following patch for Collection Studio 2.46:
http://www.collectionstudio.com/cs247beta.zip - just download and overwrite executable file from this archive in Collection Studio Installation folder. (Download of this file will be stopped when a new version of the CS will be released)
Otherwise, you can wait for a while (approx end of this week), when a new version 2.47 of Collection Studio will be ready for download from our web-site.
