Processor with conditional logic resets

After adding new processor (redirect on submission) with a simple conditional logic it only works till I try editing a form, so if I set it up and save, it will work as long as I get back to dashboard and click edit form, on that moment the conditional logic gets reseted and if I save form even without making any changes to it the redirection will no longer work, to make it work again I need to go to processors tab and set the conditional logic again ( processor itself it’s still there but conditional logic box gets empty )
