Same input, different outcome?

Hello everyone,

recently I've tried to login to a site but was unable due to wrong username / password.
I also noticed the username looking different from what I had in memory for that specific site aswell.
Now I have tried getting the login data from the web application and strangely there it worked.
On the web login I have put the algorithm on V3 (just like on my desktop app) and used same username and masterpassword.
The password for the site is same on both the desktop and the web application, only the username is different.
Could this be a bug with the new desktop app? Have I made some mistake? Any help would be VERY much appreciated!

    Note that the web app doesn't generate usernames. If you set the type to username on the web app, you're actually generating a password, just using the format of a username as the output type.

    Master Password can be used to generate (currently) three different types of tokens:
    1. Keys (eg. passwords)
    2. Identifiers (eg. usernames)
    3. Recovery (eg. security answers)

    Each of the tokens is generated through a separate cryptographic channel so that their outputs are completely distinct and unrelated (for security purposes).

    However, when generating a key, you can choose what to make the output of the key look like (the password template). If you choose Name here, you'll get a key that looks like a username, but is actually still a key, not an identifier. Ergo, to get a username from Master Password, make sure you're generating an actual username, not just a password with the Name type template. Again, the web version doesn't currently support the Identifier and Recovery type tokens, the desktop app does.
