DBC Editor fails to reopen Signal Editor for a Signal that has its name edited.

Steps:

Open SavvyCAN 214
Open the DBC File Manager
Create a new DBC File
On the default node, create a message
And in that message create a signal
Double click on that signal to open its editor
Rename the Signal
Close the editor
Double click on that signal again
The editor does not appear again, the signal is not anymore editable.

Logs:
I couldn't find a way to come up with a trace or something (please direct me if so)
But I ran the binary through terminal an these were the STDOUT:

Loaded DBC file "<Unsaved File>"  (bus: -1 , Matching Criteria: 0 Filter labeling:  enabled )
QVariant::load: unknown user type with name QList<int>.
