Select Show Only Entries Below Selected Directory to restrict the Directories/Files view to only those directories and files which are actually children of the logged directory (only available for directories).

After resolving these possible conflicts you may commit the rollback. Be sure to use a meaningful commit message which should probably mention something like "Rollback of revision #...".
