Short version: You have to click on the grid button to edit the RSLT.
Long version if needed:
Okay, do
exactly that:
* open the package with S3PE
* on the bottom of your screen make sure the tags option is on: that turns on the tag column.
* find the RSLT in the tag column
* highlight it: it means click on it once. The line will turn blue.
* Click on the Grid button that is on the bottom of the screen. The data grid sub page appears.
* in it click on the plus sign at the left of ChunkEntries
* click on the new plus sign that appeared on the line under it
* click on the plus sign on the left of RCOLBlock
I think you got it now
* click on the plus sign on the left of Containers, here's where the resources have to be added (most of the beds I did already had at least one correct entry)
I hope I'm not mistaking. I'm uploading a crappy pic I made, wait a sec'.
