Choose a type of rule which allows to use the additional_threshold_type, for example an "AND" rule
Set the threshold_type to "MORE" and the additional_threshold_type to "LESS" (and fill the other parameters as you want)
Save the rule
Edit the rule and you'll see the additional_threshold_type is set to "MORE" and not "LESS"
I have checked the POST (and PUT in case of an update) request, and the additional_threshold_type is well set to "LESS".
But in the GET response it's set to "MORE".
In the MongoDB additional_threshold_type is also well set to "LESS".
It's also set to "LESS" in the Event Definition page.
So I think the rule is working as expected.
But it can be disturbing when you display the rule in the Wizard.
Moreover it becomes a real issue if you want to export the rule with the Wizard because the additional_threshold_type will be set to "MORE".
To reproduce the issue:

I'm using the 3.3.0 Wizard version.
