mate-tweak / panel / select panel layout fails

[J]

I have made a custom panel layout jk-1 with mate-tweak: I tuned the Familiar panel and pressed save as jk-1. When I change panel from jk-1 to predefined Familiar it works OK. When I then try to change back to my new jk-1 mate-tweak prints

Switching to: familiar--jk-1-tweak
Traceback (most recent call last):

FileNotFoundError: [Errno 2] No such file or directory: 'mate-volume-control-applet'

and the tuned settings of jk-1 layout will NOT show.
It is also not possible to delete jk-1 layout with mate-tweak anymore.

When I run command line:

mate-tweak --get-layout
Window Manager is: marco
System installed layouts:
['contemporary', 'eleven', 'familiar', 'mutiny', 'pantheon', 'redmond', 'ubuntu-mate']
Current layout: familiar--jk-1-tweak

it says that jk-1 is currently selected, but no tuned modifications of jk-1 are shown.

When I try to select layout by running

mate-tweak --layout familiar--jk-1-tweak
Window Manager is: marco
System installed layouts:
['contemporary', 'eleven', 'familiar', 'mutiny', 'pantheon', 'redmond', 'ubuntu-mate']
Current layout: familiar--jk-1-tweak
Switching to: familiar--jk-1-tweak

    raise child_exception_type(errno_num, err_msg, err_filename)
FileNotFoundError: [Errno 2] No such file or directory: 'mate-volume-control-applet'

I get the same error as from running mate-tweak GUI and no tuned settings of the jk-1 are shown.
