Change default document classes when uploading documents in M-Files

It looks like you have created "Dokument Ceshtje" as a new object type and added some classes under it. Even though you may have allowed the new object type to take files and named it something with "document" the system will not treat it as a place where you can place new documents.

You should create new document classes under the built in "document" object type. When you place the new classes there they will show as options when you attempt to add new documents to the vault.

You can also create class groups under document object for more structure..
