when you attempt to import a process via design transfer.
When you initially created the export file for the process it will ask you if you want to include all dependant objects.
The way to resolve is as follows.
Firstly perform one import file of the objects/windows (either one will import the attributes manually created) then next perform another import of the process with NO dependant objects it will use the newly imported objects and create the actions from them.
