Missing data in integrated PowerApps while visible in PowerBI

Hello,

Below PowerApps was created in Chrome following the steps as described in the Announcing availability of PowerApps custom visual for Power BI (preview) but it seems that it the items from the List Box (PO Line: Part Number) are not fully reflecting the PowerBI table on the right ("Items Tracking") as below screenshot (no filters applied)

• this case, the item "1:T6043246" is missing from the PowerApps visual

 Have you ever come accross this issue?

Thanks for your help on this.
