Multiple PipelineEndpoints created with same name

I've created a Pipeline Endpoint and then disabled it. Now I'm trying to create a new Pipeline endpoint with the same name. This throws an error on console stating 'Failed to add item to collection: PipelineEndpoint' but strangely it created the endpoint which is visible on Azure ML ! I tried to update it and again I got 40X error 'PipelineEndpoint name not found' on console
but a new endpoint with same name is created again and is visible on Azure ML !
