Placeholder images for Unity Ads is being added to build

Whenever i build my project, Two placeholder images(‘portrait’ , ‘landscape’) for Unity Ads is being added to the build. I went to “C:\Users\USER\AppData\Local\Unity\cache\packages\packages.unity.com\com.unity.ads@X.X.X\Editor\Resources\Editor” and deleted both the images. Still they are somehow being added to the build every time.

Any possible solution to this problem?

Please fix this. Dummy Images are included in builds.
