After importing test sessions, the graphs don't update unless you take some action to make the screen refresh.
Some possible options:
Add an endpoint that can be used to check for changes, perhaps session count since a datetime
Add an IPC method that can be called from the backend
Areas that should be updated to use this method:
[x] Protocol import
[x] Session import
Background
Widgets use the Admin API (http) for data, this data is only fetched when session count changes (which itself is only fetched under certain conditions).
