Manipulation of Add-on via Variable

All of my timestamp-like fields I've been creating a variable to format, in a human-readable way - sometimes with time, sometime just a date.

Here I've got an add-on with a timestamp field ("step_date").

First I have a Loop that goes through 3 timestamp fields on the 'application'.

This Update Variable doesn't seem to work no matter the dot notation I try.

What am I doing wrong here?

I've also tried the existing variable application._latest_step_of_application.step_date
