@orange Hi, have you found a solution for this? I have the same problem.
"I've just recognized that, it works everytime but except first initialization of the plugin.
Because when the plugin is opened for the first time, after succesfully loading, plugin creates the user preset folders and presets.
But since presets haven't been created (because the plugin hasn't been loaded yet for the first time) on first initialization, the label box will be empty.
If you load plugin again, the label box will be ok and show - Init preset since the presets have been created on previous plugin opening.
There should be a fix for that."
