This looks like an issue in Minerva.
The following rules should address this:

.mw-changeslist-time:not(.mw-changeslist-date) {
    display: inline-block;
}
.mw-changeslist-date { display: none; }

There's also likely a bug relating to hidden/supressed edits.

@Sergius_Justus_Nyah do you have any updates that you can share on your progress fixing this issue?

Dear @Jdlrobson,

Apologies for my late reply due to health and academic commitments. I'm still searching for the specific file causing the issue on the Special:Contributions page. I suspect the problem might be due to incorrect grouping logic, timezone differences, or cache update issues. Any guidance from you would be greatly appreciated as I continue to investigate.

Best regards.

Greetings @Jdlrobson I've just gone through the release notes and seeing the file path and what's causing the issue, So I'm actually working on it. Thanks!
