RSS Image not Showing Due to Jetpack

Hi, I am using jetpack on my sub-folder domain (https://questionpapershub.com/free-job-alert/).

I am generating an RSS Featured Image using the plugin https://www.ads-software.com/plugins/rss-featured-image/ to send RSS feeds via email.

But after I installed jetpack, the feeds now doesn’t show the image. So when I checked (https://questionpapershub.com/free-job-alert/feed/), I found the URL of the image starts with “i2.wp.com” ending with a query parameter, on more digging I found that it is the photon service of wordpress.com.

I think here, that the image not shown, is due to this URL. Because I am also sending an RSS Feed of (https://questionpapershub.com/category/internship/feed) which is on my main domain (https://questionpapershub.com), it works perfectly fine and to the surprise, I haven’t installed Jetpack on it.

So, can you help me out with this? How can I make sure, my images are back in RSS Feed?

Thank You.
