Unwanted automatic confirmation of transfer order

Hi,

I am kind of out of good ideas. The problem is following:

I pick for production orders to fixed bins using several different WM movement types. When I am low on stock the production orders then cannibalizes on each other when picking in background. I dont have "propose confirmation" set in any of the WM movement types concerned.

Ex.

2 pcs are in interim storage type 914, then I generate a transfer order for interim storage type 924 (copy of 914), which picks from 914 and confirms automatically.

thanks for any ideas of what else to check.
