Table MultiSelect with spaces in target doctype name

Hi, I have a custom field on Employee Doctype of type Table MultiSelect that should take items from Project, but when I use “Project” on the field to indicate the doctype to fetch items from, ERPNext fetches them from Project Type. If I use another Doctype, Asset for example, it work right. Is this a bug? Is caused for the space in raw mysql name “tabPrject” and “tabProject Type” (the space)

Can I specify the Doctype to fetch items from in another way?
