Cannot save new Rule #8353

Hello,

I tried to add a new rule but I cannot save it.
I tried it in three different browsers (Firefox, Chrome and Edge)

When I create the rule, I can load the plugin (replace), the new fields are shown. Then I fill in the values, but I cannot save it. Nothing happens. I cannot "Save", "Save and close" and not "Save and new". I can only cancel.

When I first click the Save Button I get a javascript error in the console, see attachment.
I can save new templates - for example.

Thanks
Sigrid
