Page field shows selection as timestamp(label)

[Orkun]

I have a page field calles select_multi_dates. I set a php specific selector like this

$currentActivity = $page->parent;
return $currentActivity->activity_create_date;

It shoud give me all pages from the activity_create_date pagetable, what it does well but the problem is that the label is shown as timestamp.

And here is the configuration of the page field:

What I'm missing?

Try the custom format and put {date_from} into the field. I think this will give you another format than a raw timestamp.
