Samigo: Reordering parts is switching parts

It seems when you try to reorder parts, it switches parts. i.e. if you want to move part 5 to the top- you change the part number to 1 and click update order. It then switches part 1 and part 5.

Steps to reproduce:

1. Screenshot 1: Setup a test with multiple parts. The last part is called "part to be moved"
2. Screenshot 2: Move the last part to position 1. and click Update Order
3. Screenshot 3: New order:

• "Part to be moved" has moved to the top (expected)
• However "Part 1 is now at the bottom (unexpected)
