Datastream not saving

Hello, need a little guidance with virtual pins.
I have a PI4 running node red sending data to Blynk. Currently have a couple temps working.
Tried setting up another virtual pin monitoring a relay contact connected to a GPIO pin on the pi.
Works on node red when I energize the relay. When I try to set up the the slider switch on the web dashboard as V5 in the datastream it does not save. I have created a new datasource and then select it and save. For some reason it does not save.
Still learning, so maybe I am missing something simple.
Thanks

I think some screenshots might help us to understand the issue better.

@J2Industries - here is an example of the slide switch setup

He probably won’t be using automations with Node-Red, to the advanced options aren’t really relevant to his datastream setup.

Got it working.
I deleted the data stream and then started over.
After I deleted it I was wondering if I had the data type wrong.
Thanks for the replies.
