Normal. You can replace an alias URI with a new URI, even if it is the same URI. I consider it a bug, but CfB says it is a feature

Maybe i can't understand you properly, but i talk about two same aliases.
First is "lr127" (URI is "id:11017826896") and second is "lr127" (same URI "id:11017826896").
I wanted to buy one alias and spend 1 NXT, not 2.
But when i query:
http://node1.nxtbase.com:7874/nxt?requestType=listAccountAliases&account=11017826896I see only one alias "lr127". As expected.
