When we have an Orchestrator action that has return type "Any" and we use it in Custom Form field of a different type(for example string) in a workflow and then try to edit this form in Service Broker, the field with this action will be with deleted name of the action, because of a mismatch between field type and action return type. Also, it will not be possible to select Any typed action for this field, only string typed.

Any typed action for not Any based custom fields is not supportable in Custom Forms in Aria Automation
Do not use one Orchestrator action in Custom Form field that can return different types based on the inputs.
Form field type should match the action return type. So, create different actions for the different type of fields
