Can't delete TV Shows I contributed in the past

Hi,

I'm trying to clear some of my credits to make my imdb resume look good. There are a couple of my projects: My Colour Clones (Pilot), My Colour Clones (2015-2020) and Why, Bobby? (2019-) that are in the way of clearing and I can't seem to delete them off of imdb for good. I've contacted imdb through email and I'm not getting any replies. I've also looked up ways to delete as they involve a long process. I would like them off of my imdb because they are not projects I'm fondly proud of. Is there any easier ways to go about doing that? 

Here are the links to the shows I would like off;

Why, Bobby?
