Hi OM,
It's standard. If you don't have anything to split & Putaway qty = LE qty.1, system would only display SUT1 as we don't need SUT2. But, still you can alter manually if you want to palletize with SUT2.
Also, please be informed that we can only use LEqty 1 & 2 as LEqty 3 is meant for Bulk storage block structure.
Thanks,
Venn
