Node Spin error

Setting up a large fixed wing.

7 can nodes.

In DronecanGUI on the bottom of the main screen I get an error. Does anyone know what it means?

Bit value and frame number seem to change as it cycles through.

“Node Spin Error - [1 of 1000] :TransferError(‘Toggle bit value 0 incorrect on frame 5’)”

“Node Spin Error - [1 of 1000] :TransferError(‘Toggle bit value 32 incorrect on frame 2’)”
