Subpages numbers duplicate when drag'n'dropping

Hello everyone!
I’ve started using Kirby just a few weeks ago, but I’m really excited about how cool and simple it is.
Unfortunately, I’ve faced the next situation:
One of my pages contains multiple subpages, so I see pagination in panel. But when I add one more page to the list, it duplicates subpages # on the next section of pagination. I can’t add images to the post, so you can see what happens at http://take.ms/UlyrR.
Did anyone meet this problem before? I will highly appreciate any help.
Dmytro.

Have you tried this with the nightly builds of the panel (aka version from the https://github.com/getkirby/panel/tree/develop) – cause I think this could have been fixed here: https://github.com/getkirby/panel/commit/fb7eefeaaa89834a822149b5484d4b9244b920a9
