Not a bug, the problem is that the expression generator has a feature context where it shouldn't have one to reflect the legend.

Thankyou for the response Alex. I don't really understand though, you might have to dumb it down for me haha. Is there a way to achieve what I want without having to manually type the other field value into the legend items?
Depends on what you're using for the symbology. If it's only a single field you can use the collection function with the filter set to replicate the symbology rule used and pick the first element of the returned array. Though for that to work at the moment it will work in your symbol label is exactly the same value as what is used to perform the classification.
What is the bug or the crash?
When trying to set a legend item with an expression to rename to another field value the legend displays the expression rather than the target field value.
Steps to reproduce the issue
Set legend to auto update and only show items inside linked map:
Expression for the target layer and confirmation it is valid in the preview:
The legend in the map composer showing the expression rather than the target "unitname" value:
