Error 5 in Qlik Sense page mooving (bug?)

[Marco_Imperiale]

A possible bug:

1. Set a page as private into a group
2. Publish the page
3. Move the page in a different position = Error 5

But:

1. Set a page as private not in a group
2. Publish the page
3. Move the page in a different position = Ok!

See attached video.

Some help?
