Hi, I accidentally put negative feedback, changed it using Feedback revision request but it wasn't updated.

Go back and try again. Be sure to check on whether there is an extra step to save or confirm the change.
If you don't manage to change it, then the seller can complain to eBay and can get it removed because your comment ("everything is fine") is positive not negative.
