Dify version

v0.11.1

Cloud or Self Hosted

Cloud, Self Hosted (Docker)

Steps to reproduce

As shown in the diagram above, when input class b is entered, it outputs Class AClass B. The answers from other branches are also outputted together. Based on my tests, the output is correct if there is no Variable Aggregator node.

P.S v0.10.1 is ok even with Variable Aggregator node.
