I have created a Reusable Workflow in SharePoint Designer 2013 using workflow 2013. I chose a Content Type for this resusable workflow since i need to use its columns. Next day i open the workflow and see that no content type is assigned to it but changed to All. I can't choose to assign a content type to it.
Is there a way to fix this? I've searched the web and it seems that other members have the same bug as me.
