This is caused by Facebook “Scrape information” cache. I tried sharing the product of which you posted a screenshot, and there really was “BY PIXEL INDUSTRY” written underneath it.
I then opened the https://developers.facebook.com/tools/debug/, inserted the product’s link and clicked “Fetch new scrape information”. I checked the share dialog again, and now it says “BY SANDRA PINO”.
Facebook will periodically refresh the scrape information, but sometimes you need to do it manually. Just insert your link and fetch new scrape information and everything will be fine.
