Plugin Showing wrong 404

That URL is being redirected:

https://redirect.li/http/?url=https%3A%2F%2Fwww.outfittrends.com%2Fbeach-party-outfit-ideas-for-women%2FNoadcouldbefoundmatchingthisrequest

yes , i have 1000s of those urls , they are being redirected

the issue is

then they should not appear in 404 any more , rather than , in logs

but still all those url are showing in 404 section

Can you show an example of one of this appearing in the 404 log?

the url i mentioned above is showing in 404 section , although its being redirected , i deleted it from 404 section , cleared all cache , but it appears again

Sure but can you show me a screenshot of this?
