Teamleader Empty items_price_per_unit field in V1Flat.SubscriptionItemsAll

I am connecting from PowerBi to Invantive Bridge Cloud via ODATA4. I am syncing multiple tables including V1Flat.SubscriptionItemsAll (there isn’t a V2 table that contains line items (nor custom fields)) but the field items_price_per_unit is “null” for all rows despite subscriptions having data in what this field should be.

Power Bi query editor:

Where’s the bug? Is there a plan to make a V2 table? With custom fields and line items?

Thanks in advance
