Memory card not ejected after import

Hi, for the first time in one year I have imported photos just like any other time, and after the confirmation sound, the card was not automatically ejected.

No error was displayed and the card ejected just fine when I did it manually via Finder. Any idea wcould have caused it?

Thank you.
