This is because all the actions that are programmed into the panel, that open those dialogs and some debug messages that the author put in there get triggered when loading the exported instance.
A solution would be to ask the author of the panel to take into account the initial state of the panel (there is a special Lua function to check if we are loading), so that those actions don’t get triggered on load.
I’m not sure if it’s possible to do a fix inside Ctrlr to prevent that, since Ctrlr sets the initial state for all the controls on load, and those controls show those dialogs, can the author of the panel write if this is intentional or maybe it’s a bug i did in Ctrlr and i can fix (perhaps those checks i wrote above are there but they are just not working?)
