More links for block display disappeared after update from 6.X-2.X-RC1

I have tried to disalbe and enble the module, clear the cache, both don't make sense, is there anybody can help me?

The value of Items to display is 5, I have tried "Use default" and "Override" method for More link, both can't chage current state.
There are 13 item in the page that block display link to.

It maybe only my problem as nobody alse ecounter this. But what shoul I try to do for resolving it now?

Thanks so much~ Here it is.
There are 4 displays in total, 2 are block and 2 are page, each block link to a page. But none of these two block displays has more link after updating.
