SellingPlan Billing Policy For Deposits Not Applied Correctly

[chrismgala]

A merchant notified us of an issue when using our TBYB app.

They opted to use our deposit option and noticed a discrepancy between 2 checkout scenarios:

Checkout 1 (TBYB only)

1. 1 TBYB item
2. Correct itemization (deposit due immediately and full product price due later)

Checkout 2 (Mixed cart)

1. 2 non-TBYB items
2. 1 TBYB item
3. Incorrect itemization (deposit is higher than expected and deferred payment is lower than expected)

In the mixed bag checkout, the “Due today” amount should be $99.95.

The deferred payment should be $60.

The difference is $9.95 which is what they configured as their desired deposit amount when the SellingPlan was created.

Here is our SellingPlanInput for the sellingPlanGroupCreate mutation:
