credentials are invalid dataflow

I see the following error for one of my dataflows

Your data source can't be refreshed because the credentials are invalid. Please update your credentials and try again

In reality, each of these highlighted datasources are already removed from the dataflow. Despite being removed, why do they show up here. My data refresh is happening smoothly. But why does it show up here and it is very confusing.

What is the workaround here without having to replicate this dataflow cause I have massive depenedencies to this dataflow and I don't want to establish a connection to all those to the replicated dataflow
