Sentry.io - View Issue - Default Environment Case Insensitive

When viewing an issue, at the top of the right hand panel, I have 2 environments I can select in the dropdown.
- `Production`
- `Production`

When I select each one in turn the url changes:
- `https://sentry.io/mem/hivehub-web-prd/issues/404903591/?environment=Production`
- `https://sentry.io/mem/hivehub-web-prd/issues/404903591/?environment=production`

Note the case difference (`p` <> `P`) in the URL.

My default environment (as configured under project settings) is `Production`.

How my account got into this state, I'm not sure, I probably changed the case at some point. This **isn't** the reason for raising this case.

This is the issue, when I visit the URL (without an environment argument) -
`https://sentry.io/mem/hivehub-web-prd/issues/404903591/` - I don't get my default environment. Instead I am looking at `production`.
