Please download the file “DFFS_2017-06-29_Incremental.zip” from here and replace the files in the current DFFS folder (if you use a custom folder name, it goes here).
This fixes the hover icon for the tooltips, and an issue with setFieldValue for multilookup fields when you use multiple setFieldValues on the same field. Earlier this would only work for the first one.
Let me know how this works out.
