I found a similar unsolved discussion regarding the Node Variable Aggregator not extracting multiple variables in multiple rounds of conversations. You might find it helpful to check out this discussion for any insights or updates ^[1].

For your specific issue, ensure that the Node Variable Aggregator is configured correctly to aggregate variables of the same data type, as it can only aggregate variables of the same type. If the first variable added is of a specific type, subsequent variables must match this type ^[2]. Additionally, check if there are any constraints or limitations that might be affecting its functionality in your setup ^[2].

Duplicated, the variable aggregator will not merge things together as you expected.

In your case, you just need to remove the Variable Aggregator, and it will merge things automatically.
