Repository deleted and recreate, name issue

I am using 3.25.0-03.
I have a p2 proxy repo which I deleted and then recreated with the same name and settings.I’m using the repo with Eclipse.
After I recreated, the repo won’t populate and have the same errors before the repo was deleted.
After I created another repo with different name and the same settings , it worked and the repo is populated and I can use it in Eclipse.
When we delete the repo it is possible that something remains , I don’t know, maybe cache ?
How can I get through this issue? I need the same name for the repo, changing the name would mean a lot of work.
Thank you.
