To reproduce the issue:

1.  Open Assets --> Scanned Software

2.  Check the checkbox on 1 or more entries

3.  Change the “Move To:” dropdown box to the desired Type

4.  Click the “Move” button

Once complete, repeat the process again on 1 or more entries.  When you click the “Move” button for the second time, the selected entries are not changed.  NOTE:  In addition, after this action is performed, most “Filter” dropdown boxes for any list in SD+ (e.g. Requests, Purchases) fail to work.  The only way to get them to work again is to close the browser.
