Whoa totally bizarre! I can reproduce the issue.

Rewrite of the global shortcuts kcm

Summary:
This is a total rewrite of the global shortcuts kcm from scratch. It uses an
abstract item model backend with a qml frontend. This resolves some issues the
old kcm inherently had because it just stacked KShortcutEditors. First it enables
a global serach/filter which either matches the component name, actions, default
or set key combinations across components. Secondly KGlobalAccel can have multiple
default/active key combinations for each action - the old kcm only exposed two each.
The new kcm displays all default or set key combinations.
The main visual structure is similiar to the old kcm. On the left there is a list
with all components but rather than divided into "Application Launchers" and
"Other Shortcuts" the sections are now called "Applications" and "System Services"
(cf. notifications kcm) and the components are now assigned whether the service
we find for a component is an application or not rather if the component was
added via .desktop file. In the main view the shortcuts are displayed. Each item
corresponds to one action. Initially each item is collapsed and shows the action
name and a list of the currently set key combinations for that action. In the
expanded form all default shortcuts are shown which can be activated or
deactivated and all other active shortcuts ("Custom Shortcuts"). It is possible
to change, remove or add new custom shortcuts.
The kcm and model communicate directly with the daemon over DBus. This removes
the need to awkwardly construct actions to pass to the KGlobalAccel API.

new Global Shortcuts kcm on Plasma 5.19 beta

This issue is still reproducible with the new Global Shortcuts kcm.
My screenshot shows the "System Settings" category selected and "Launch Konsole" (without ctrl+alt+t shortcut previously configured) in the right pane.

Operating System: Arch Linux 
KDE Plasma Version: 5.18.90
KDE Frameworks Version: 5.70.0
Qt Version: 5.15.0 rc2

Urgh that's a "feature" of kglobalaccel made worse by the combination with khotkeys. 
KGlobalAccel has the concept of an uniqueName and a name that is displayed to the user. If it receives something with a known uniqueName and a different display name it will update the display name to that. Useful for example when switching languages.
What's happening here is that khotkeys stuff doesn't seem to set an explicit display string defaulting to the one of the process it's running in. On start the shortcuts are registered by the kded module so you get "KDE Daemon" but if you open the Custom Shortcuts kcm, it will register all it's hotkeys with kglobalaccel  with the displayname of "System settings" because the kcm is running in the system settings process ...
