Problem with Classic Editor and WPGlobus

I run a multilingual site and I use WPGlobus to organize the different language content. To create and maintain the articles I use Classic Editor. Recently I realized that the Classic Editor did not work a I was used to. The visual editor area was empty when I opened a article. To resolve this problem I have to switch to text editor, press reload, and then I can switch to the visual editor, where now content is presented.
This error is gone when I disable the WPGlobus plugin. This problem is independent of the browsers, at least I tested it with Firefox, Crome and Opera.
Is there a way to resolve this problem?
