Do the comments still show after you empty your own browser’s cache too? That seems less likely to be the culprit, but worth a check to be certain.
Elsewhere in this post there’s also a helpful user who notes that the mass-editing programs can only handle a thousand comments. Is it possible this is why some of your comments are still there?
They said the originals do not appear on their account on Reddit. They also said they edited their original posts to be empty. They’re able to edit and delete their modified (empty) comments based on what I understand of their post.
I don’t see anything in OP’s post that indicates Reddit.com itself is displaying the originals, only the search engines are, and the cache would be the reason why.
Search engines do not scrape the entire internet every single time someone searches. They do routine scrapes of web content and create a cache of what was there, and search that cache. This is why updates to websites do not always reflect on searches.
You’re contents are findable on Google because the last time they bothered to scrape that particular Reddit post was when your comment was intact, and they have not had a need to scrape it again since then.
Some dishes freeze well, so those leftovers can be turned into future meal prep. I liked freezing my chili in silicone muffin tins, then one or two thawed chili pucks was a perfect last-minute meal when I didn’t feel like cooking.
