EDMCS: Trouble removing a property from a Node Type (inclusion property in subscription)

Hello, I'm trying to remove a property from a Node Type but im getting the following error:

The following properties can't be removed from the node type because they are used in an inclusion property filter for an active subscription: 'Enable for CdF'

This used to be true since this property (Enable for CdF) was used for the inclusion property in a subscription, but i have already changed it in the subscription to another property (Is Level 0). I would like to add that there are no active requests at all in the application and there are no more subscriptions that use the Enable for CdF property.
