Caption 5: Vertical position 22 exceeds the Maximum Number of Displayable Rows - 11 as specified in the GSI Block
The EBU asset contains a row position greater than the maximum number of displayable rows.
Traditionally we automatically override this warning as we are able to accommodate the discrepancy and create a useable file without any further action from our Partners.
You should not receive a rejection where this is the only issue listed. The most likely scenario where you will encounter this error is when an STL file fails for multiple reasons e.g. TimedText-TimestampWentBackwards. In this scenario you can ignore this warning and address the real blocker. This warning will not surface unless there is a legitimate ingest blocker affecting this asset.
