Insert Dynamic content selection not passing data on execution

In the flow below, some updates to target fields work when previous step inputs are used and some do not.

Green - works fine, yellow - no updates/no errors.

Where the updates in yellow do not work, if I replace with "test in quotes", this does work, validating that the target is correct.

I used / to Insert Dynamic content and selected desired data to transfer from the Dialogue box presenting fields from work items in previous steps

Do I need to edit default syntax for this to work?
