### What happened?

An `This feature is only available for LiteLLM Enterprise users` error occures even when no enterprice features are used when i try to edit an already created virtual key by e.g. adding a model to the key.

In earlier version of litellm i could add models to keys without any problems even without an enterpice license and according to your website it should still be possible.

I attached a video showcasing this behaviour.
