@Patrick Zweekhorst found a bug when pushing an array of tokens to a list with a non-dynamic label field.
In the attached model, we create 6 tokens with an "index" label of 1 to 6 and push them on a list. The list has a non-dynamic label field to show the index.
The activity block on the right pulls all 6 tokens into an array, and then pushes the whole array back on the list. The labels on the tokens are still correct, as you can see by clicking the green dot on the list and inspecting the values, but the value of the list field is set to the label value of the first token for all tokens.
Discovered in 16.2.2, but still seems to be present in the latest 2017 beta.
