You sent one file and Rhodes filed four.
That's intended. A lot of what arrives at a family office is really several documents in one envelope — a tax package holding a return plus six K-1s, or a fund's year-end bundle. Rhodes splits these on page boundaries and files each piece separately, so the K-1 for one trust lands on that trust rather than on whatever the cover page said.
Each piece is filed as its own document and can be renamed, refiled or searched on its own. The original stays intact underneath.
Splitting goes at most two levels deep. A document beyond that is read whole rather than divided further.
If only some pieces could be split out, the row shows as Stuck and the original is left as it was. Cancel it and upload the file again to start over.
