Missing buttons move / delete on app chooser

[NietGiftig]

Use a couple of this launcher on the desktop, good enhancement, thanks for that
I think there is something missing in the app chooser (in my configuration of-course)
I do not see the buttons to move or delete items, attached a picture
I accidentally found out that they exist when i clicked in the space behind the app name.
I am using :
openSUSE Tumbleweed
KDE Plasma 5.12.5
KDE Framework 5.46.0
QT 5.10
Workspace theme Breeze

Any suggestions?

I also need to remove some application, but now it isn't that button.
So I have to remove all and readding each application.
