Bucket with given name still exists

I’m running Couchbase Version: 2.5.1 enterprise edition (build-1083-rel) 2 server cluster on Windows

I created some test bucket to play with it. After some experiments I decide to “purge” it by delete|recreate.

Now I can’t recreate bucket with same name - still getting “Bucket with given name still exists”. I discovered folder with bucket name still exists on secondary server in cluster (30 minutes after deletion). I tried to delete this folder manually without restarting Couchbase. Deletion was successfully but I still can’t recreate bucket with same name (still get “Bucket with given name still exists”).

WTF?! How to fix this?
