Thank you for your feedback. This bug will be fixed in the next release. As a workaround I recommend you to set the default operation visibility to public.

Open the Options dialog - File menu / Options

Switch to Diagram Editor tab

Choose "public" from "Operation visibility" dropdown (it is available in "Default settings for elements" group).
