CKEditor doesn't load in custom [[*content]] fields in MODX admin panel

[Max]

Maybe there's a plugin for that. But I could not find any related to this issue. I have CKEditor installed as a default rich text editor. I also have Xlexicon MODX add-on installed. It creates "duplicates" of all resource fields and uses them for additional language storage. I can then use the content of these fields when switching the language of my site. But unfortunately, CKEditor doesn't recognise additional *content? field as a frame where it could be loaded. I tried another editor, TinyMCE. It does recognise those fields. But I don't like it. It breaks my formatting. I prefer CKEditor over it. Please figure out what's wrong with it. Thanks
