Diagram all messed up after saving and reopening.

I made a diagram in a microsoft word document. Saved my document. Closed libreoffice. Re-opened my document and the diagram is all messed up. What is going wrong?

Please provide more information and have a look at What information should I include in a question in addition to OS and LibreOffice version? - #4 by ROSt53
OS version? LibO version? What kind of diagram and how did you create it?
