Incorrect unitCost value returned by the API for Credit Notes

Hi,

We're consistently seeing missing UnitCost values for Credit Notes returned by the API.

We rely on the API to export data into our data warehouse for BI reporting, but this issue is making it difficult to accurately calculate Gross Profit and totally degrading trust in the accuracy of data within Cin7 across our business.

I've raised this with support multiple times, but so far there's been no sustainable solution.

Has anyone else experienced this, or found a workaround that works?

Thanks
