I tried the file manager sync (recursive) for syncronising ftp files with dnn

it didnt work and gave me the following error

INSERT statement conflicted with COLUMN FOREIGN KEY constraint 'FK_FolderPermission_Folders'. The conflict occurred in database 'DB_xxxxx', table 'Folders', column 'FolderID'. The statement has been terminated.

Then i checked update logs and find the following issue under 4.03.03 log
