Wording in Generative Fill in Counter-Intuitive; also basic fill functionality fails.

App Version: I cannot tell. Whatever on available to Chromium web browser on 07/22/2023

Platform: Windows 11 

I tried to use Generative Fill to replace (fill) some background objects, including a blue rope barricade. The left-hand buttons on https://firefly.adobe.com/generate/inpaint (insert, remove, pan) were confusing. I wanted to _replace_ the rope barricade.

I set the brush to a smaller size and brushed over the rope barricade.

I clicked Insert and then Create; result: nothing happened.

I clicked Remove and the Create; result: nothing happened.

Suggestion: Use other nomenclature, such as Replace Selected Object rather than  Insert and Remove. ( A generative fill is basically doing BOTH.

I have a screenshot, but I am not signed in, and I will lose my writing to sign in.
