Stripe Plan name shows as "default"

I have created a test plan in my stripe dashboard with the name "Enterprise Monthly" and done a fake charge for team billing. When had a user subscribe to this plan, the resulting spark data for the team, the spark data for Spark->State->Teams->[0]->subscriptions->[0] was as follows ...

....
name:"default"
provider_plan:"my-id-#"
quantity:2
stripe_id:"XXXXXXXXX"
stripe_plan:"provider-id-5"
team_id:4
....

I expected the Spark name variable for this subscription to have the formal name of the plan ... like "Enterprise Monthly" or whatever name I give it in the setup for the product. I don't know why the default is there.

Any suggestions? This is test data if that matters.
