Would you be able to share the API response for the monitors/ API request?

Specifically I'm interested in if the [].evironments key has two environments in it, or if this is a UI bug

Hey, sorry it took me so long, there really are two production environments in the API response:

I just created another issue that might be related: #3104

Hi @JeremiaAu

It's pretty unusual that you have duplicated environments here. We have unique constraints to prevent this type of duplication - the main way I could think of this failing is that potentially you have environments with the same name in multiple organizations in your self hosted instance, and possibly you migrated the monitor over and something went wrong with the migration.

Does that sound like something that would be possible in your set up?
