Hi Ollie.
As far as I can remember FL130 at LAM is reserved for KK deps via LAM. LAM sector has to keep the level clear for those transits, and avoid them when descending traffic in the stack. In real life this traffic will be climbed much earlier so it can jump SS AND GW inbounds via VATON.
Similar to KK inbounds that transit OCK at FL150. They don’t speak to OCK, but need to be avoided.
I am far behind in applying my updates at the moment, so I can’t see if any of the data files changes affect this traffic.
Hope this helps, C
