儲存檔案後再度開啟，檔案內連結檔副檔名不完全

Hello @poyuan_1923,

Thanks for reaching out. Could you try installing the latest version of Illustrator / Illustrator (Beta) to see if you continue having this problem after relinking and saving your file? If the problem persists, please check if this is limited to a specific file/ files from a specific folder location, so we can better assist you.

Looking forward to hearing from you.
