Actually, there is no reason for any one to go into the database to edit values. I will have to run some tests on an IIS server to see if I can replicate your issue. To be honest, it is actually a bit hard for me to understand what it going on from your explanations. Could you provide a screenshot of what is happening?
To be honest, the list of folders that should show is set to the default of what Joomla determines by the folderlist field. That aspect is not my code. but rather Joomla’s built-in code. However, if you link some screenshot so that I can understand what is actually happening.
