“Delayed data” shows with Real-time selected

What you see. The status bar says Delayed data although Settings → Connection → Market data type is Real-time.

Why. IB reported no market data subscription for that product, so Tented switched to delayed. (With Delayed selected, this is by design.)

What to do. Click Manage subscriptions to open IB’s market data page. After you subscribe, click Reconnect: a fresh connect checks for live data again.
