Missing icons in filmstrip
Hi everyone!
I am getting crazy.
Since some time I am missing the icons to enable the second screen and the filter menue just above the filmstrip.
It is a element combined with the filmstrip. I can hide/unhide the filmstrip.
In the manual there ist the following picture:

This is how it looks on my mac:

Deleting /Users/%username%/Library/Preferences/com.adobe.Lightroom6.plist brings the icons back, but after some time they disapeared again.
Where can I turn on/off those icons?
Thank you very much in advance for your patience with me...
Kind Regards,
Bruno
