How to reproduce:

1. assign puppet environment to organization
2. go to organization details, in environments check "All environments" button
3. go to environment details: the organization is unassigned from the organization.

With this behavior, checking the "all environments" lead to loosing the whole information about the originally assigned organization. Unchecking "all environments" later would end up with organization without environments.

Expected behaviour:

The organization assignments is preserved when the "all environments" is checked.
