API payment filtering

Hello,

I am using the 2022-07 API and having an issue with a basic filter on an api call

I am trying to filter transactions via the payment_status field which should be possible according to the docs however it is returning result’s that don’t match the filter, support were not very supportive, am I missing something?

the call is being made to

shopify_payments/balance/transactions.json?payout_status=in_transit

It does return in_transit transactions but also ones that are set to paid
