I have twice seen questions which seem to ignore the subtraction of down payment in interest rate problems.
For example, a $1,000 loan with a 20% down payment should have its interest calculated on the remaining $800 dollars. Let say the simple interest rate was 10% annually and there were 10 payments, this should be 10 payments of $80 dollars, but in the questions that I have seen, it indicates that it is 10 payments of $100 dollars.
Is it GMAT convention to not subtract the down payment amount when calculating interest?

Seems to be an example of this, and I have seen it elsewhere as well.

No, these questions don't ignore the down payment. The calculations are different here. Let me explain:
When you take a payment scheme where you pay in a staggered manner, obviously you pay some interest on the sale price. Say I buy an object of $1000, I might need to pay a total amount of $1200 over 11 months. I have to pay extra to account for the delayed payment. So schemes are built by including the interest.
The first scheme includes a downpayment of 20% of the purchase price and 10 monthly payments of 10% each
In this case, if the object costs $1000, you will pay $200 downpayment and then $100 for 10 months i.e. a total payment of $1200.
If you subtract the downpayment before giving 10 monthly payments of 10%, you pay $200 and then $80 for 10 months. You end up paying $1000 total.
The schemes don't work like this. They are structured in a way that they don't mention interest but they do charge interest. They make calculations easy by giving you details all based on original sale price.
