Part Time Phase shows mixed parts

We are in Vantage 6.1 - patch 511. We have this sales order that has 2 parts
- 1 manufactured (Line 21) and 1 purchased (Line 18). If you look at the
time phase for the manufactured part (line 21), it shows a demand from line
18 which is the purchased part. Is anyone experiencing this issue?

Thank you.
