sql server - NoSync subscriptions will need to be dropped and recreated

I am having this error message from the sql server replication monitor:

Error messages: The subscription(s) have been marked inactive and must be reinitialized. NoSync subscriptions will need to be dropped and recreated. (Source: MSSQLServer, Error number: 21074) Get help: http://help/21074

The publication is SupplierDB.

I have just generated an snapshot, as you can see on the picture below.

any ideas?
