Featured images created using AIomatic plugin are not getting shown in the posts

Hi Aiomatic team, I have posts that are already published. I need to just update the featured images of those posts using Aiomatic stability api. I need to do this process manually. I tried this, my api credits are getting burned but still the featured image is not getting updated. Whenever I am trying to update the posts manually, I am getting a red checkmark. but in the posts featured image is not getting updated. How can i resolve this?
