And the reason for these credits to be removed please.
Also this is IMDb Policy on credit removal.
IMDb aims to be the most comprehensive and reliable source of
information on movies, TV and celebrities. We are committed to accuracy
and it is our longstanding policy not to alter or remove correct
factual information from our records. If you notice an error or omission
in our data, please submit a correction or deletion via the "Edit page"
button located at the bottom of every name and title page and our staff
will be happy to review it and make all applicable changes.
However, IMDb will not remove accurate information. If you try to delete an item of data which is accurate, your delete will not be processed. Please be aware that attempts to delete accurate data will count against your overall accuracy rating and may result in all your submissions taking longer to process along with additional proof requirements.
However, you can emphasise other work via your "Known For" section if you have an IMDbPro subscription, please see https://help.imdb.com/article/imdbpro/manage-your-imdb-page/manage-your-filmography/GH8XTYSWKU2P96TA?ref_=helpsrall#howtoedit (or visit https://pro.imdb.com/known_for directly).
As Col pointed out, with IMDbPro you can ”build” your personal resume/CV, but normal IMDb is not a resume service. One simply cannot choose what credits are displayed on the IMDb name page.
But yes, IMDbPro is a paid service. But it’s widely used among the industry. I believe there’s a free ”trial” with IMDbPro.
