Here is the command for the negative layers
AUTOSLOT isn't something we want scheduled, I believe what is happening is related to the timing of the scheduled job LYMRGLAYR and invoicing. What LYMRGLAYR does is merge negative layers with corresponding positive layers that are in the pick location. However, if the job runs before picking is finished, then the layer hasn't been made negative yet to merge.
What I would recommend doing when you see these commands is run this command .
LYMRGLAYR RUNLYCOM(N) ALLLYRS(N) YNREL(N)
This will give you a spool file that will let you know which locations it would be updating. If you are comfortable with all of these locations, you can run this command to have the system update them for you.
LYMRGLAYR OPTION(UPDATE) RUNLYCOM(N) ALLLYRS(N) YNREL(N)
