When you move any items in the amount of up to 60 pieces and another empty bundle into a bundle, when you click the RMB, an empty bundle first falls out, and then the remaining 60 items

Are you sure you didn't put the first bundle into the second one?

If I put the first bundle into the second, it works fine. I made a video with this problem, but I can't send it to my report, 'cause of issues of memory.

You can also upload the video elsewhere and link to it here. It would be very helpful to understand what your issue is.

Here's the video: https://www.youtube.com/watch?v=ET0PFcchyoc&feature=youtu.be

Bundles work differently now
