That is indeed not ok.

The  issue is that in the config there is a reference to the wrong wysiwyg. Now not able to dive into this but it is in the template or config file. And it needs CK editor

Which will be fixed in the 05.02.00 Release.
Alternatively you can fix it by copying one file (see Sacha's response on github)
Of use the CKEditor instead of wysihtml editor for the field
