Publish in page without mention/tag linked

Hello,

I have last version on WordPress and Facebook plugin. I want to use Social Publisher and I setup a app on Developers Facebook and the publish action is accepted today but when I write a custom text to publish in my Page of Facebook with @ mention/tag to another page or person doesn’t appear the list to choose the page. If I write in text box to publish in my timeline appear the list and convert to @[ID-of-page] but if I copy paste to text box to publish in my Page when publish in Facebook page appears @[ID-of-page] and don’t the page linked.

In my timeline appears okay.

How can I fix this?

Thank you
