Interface little issue

[Zanotti]

I found a small issue in the interface. If I fill out all fields under the "Aliases", but if I forget to insert the CIDR and save the settings, a error message return back correctly in network but also it shows a "/" near the IP filled in the same field.

Here's the screenshots. Next If I insert a CIDR as required, but i forget (can happen again?) to delete the "/" a new error appears
