All columns shows numbers

I use “Codepress Admin Columns” together with Pods. At the beginning, the column shows the right custom field value which I created by Pods. But when I add some records, I found all columns show numbers such as 6, 1360997142:6 6, 1360997142:6 6, 1360997142:6 6, 1360997142:6 6, 1360997142:6 instead of the value and Custom Field & Field Type disappear when going to setting>Admin Column.

And when I fill all custom fileds for at least one record and submit it, I find I can set the Admin Column, Custom Field and Field Type again.

I wonder whether it is because of Pods field type File/Image/Video(I choose Plupload for File Uploader) under Relationship Media. Because when I leave the value of this type blank, the problem comes. When I upload some doccuments for even one record,I can set the admin column again. But this problem appearances from time to time and I have to resubmit the reord with media to make it work.

I’m not sure whether I make it clear
