Hi Mohammad,

Thanks for reaching out. Would you mind sharing more information about your workflow? Does it happen with a specific file or all? Please share version of OS & Illustrator as well.

This information would help us assist you accordingly. Looking forward to your response.

Have you embedded the files or linked them? Is the problem when you are re-opening the file?
