Problem with removed interactions

Hello, all bots have the same problem: In the block "conditional connections" the field "then go to" was deleted. It is empty. When I insert a connection again (no matter if an existing one or a newly created one), the error message "This connection is broken, it may affect the bot scenario. The message remains and cannot be removed. After "then go to" "removed interaction" appears in red although the interaction is present in the "then go to" field.
