If you clicked on a sponsored link that said Thai airways, it obviously took you to the Thai airways website, so I guess the link you clicked was for Eva air.
I flew in August and also checked through Skyscanner. Selected several links with multi choice agencies, and at the checkout the price was always worse, or with lesser conditions than directly from the airliner.
After 4 tries I gave up and booked directly with Emirates through such a sponsored link
Another tip is to always use private browser when searching Skyscanner, and have location disabled. Don't login with Google account when requested.
Otherwise the deals will get worse with every search
