Incorrect discount amount for child product VM 2.0.24

[solmab]

Hi

Joomla 2.5.6
VM 2.0.24

Did a search but can't see anybody had this issue. I have attached 2 screen shots.

The discount calculated for the child item with overwrite final ticked, shows incorrect discount amount at checkout.  Please note the discount calculation works fine if the item is not a child item.

Please advise how to fix this.  Thank you for your help.
