Unable to move multiple files at once

How to reproduce:
1. Go to file manager (“Files”) on the panel (https://panel.ultraservers.com)
2. Select multiple files
3. Click “Move” button
4. Select directory to move the files to
5. Click “Move” button on the pop-up window
6. Files will not be moved

Expected result:

Alternatives:
