In LR 13.3, the History panel still uses pre-LR 13.3 terminology, referring to the tool as "Heal" rather than "Remove". Here's a screenshot showing the application of all the different Remove modes with and without Generative AI and Object Aware, and then deleting them: Remove, selecting Generative AI, Remove Object Aware, Remove Generative AI + Object Aware, Heal, Clone.
The History steps also refer to "Gen. Remove", though the Remove panel uses the term "Generative AI". In general, the terminology is ambiguous and confusing, e.g. using "Remove" to name both the panel/tool and one of the modes, so being precise will at least reduce confusion a little.
There may be other History steps still using the old terminology -- I didn't do an exhaustive search.
