Disappearing static clutter in self-made mod

[JustCaroAnon]

I've been trying to make a couple of warehouse cell mods for a while. The idea being, I can place statics from other mods or resource packs in the cell, and then use Jaxonz Positioner to copy them for my own use (rather than trying to edit them into player homes or the world). 

 

I've so far attempted to do this with statics from the ZaZ pack, Sisterhood of Dibella, and the Modder's Resource Pack from the Nexus.

 

I've been copying DLC2RRHoldingCell and renaming it (properly, by pressing F2 with the cell selected in the cell view window, as well as changing the name and allowing fast travel in the cell edit view) then removing the safe in order to use it.

 

When I placed the statics from each of these, they seemed fine in the CK. I saved my ESP, and tried COCing to qasmoke first (from the main menu), then COCing to my added cells. 

 

The ZaZ warehouse is working fine, with all statics present. The other two were empty - the statics had disappeared. And when I loaded my ESP in the CK, the statics were also gone.

 

I know that I saved the ESP after each edit. But I redid those cells anyway, making sure to save and close the CK after each one was complete (just in case it was something weird with the CK). On the second test, again, the statics had vanished from the SoD and MRP cells, but not the ZaZ cell. 

 

I Googled it a bit, and most people seem to be having this issue with very large statics, or statics placed outdoors. I'm not doing either of those - if anything, most of the statics from the MRP and SoD are smaller than the ZaZ statics, and they're definitely indoors. I checked the properties of statics from each mod, and they all look the same to me. The only plausible issue is that the pivot point of some of the statics might be outside of the walls of the cell, but that doesn't explain why the ZaZ statics are fine (and the pivot points of some of those are definitely outside of the wall). 

 

Why does my clutter keep vanishing, and how do I fix it?

Posting this for anyone else who finds this topic or is having the same issue: the problem was that I had to convert the ESP for Sisterhood of Dibella to an ESM. This can be done in Tes5Edit. ZaZ worked because it's already an ESM.
