This is an expected behavior because of the linear data flow that LabVIEW follows.
A Feedback Node is automatically created, for instance, when connecting the output of a node with the input of another node which is supposed to execute first.
You can disable the automatic feedback node option by unchecking
the "Auto-insert Feedback Node in Cycles"
by following these steps:
- Open LabVIEW and select Tools >> Options
- Select Block Diagram from the Category list
- Uncheck the box next to Auto-insert Feedback Node in cycles
