When ordering more than 1 product that is a part list the stock amount of the parts is deducted in more than it should.
For example, a kit product X made of:
1 Product Y
1 Product Z
If you order 2 products X the stock should be deducted by 2 in the product X and in the product Y and Z.
What happens is that product X stock is deducted in 2 but product Y and Z stock is deducted by 4 each (2 x 2). If you order 3 products X the products Y and Z are deducted in 9 each.
See video of one example:

I’ve tried this in 9.4.11 and also in 9.4.15
