Now that this is here I'll post my hypothesis. I'm like 95% sure both series are ending, no transfers nor tricky stuff, even if it could still be possible. The thing is now, what would a transfer imply? Because if we took Mitama, which is the most likely series to transfer, and got it into Jump+, the serialization would have no need to stop and it could still have its IDs placed there, then get moved to the usual Jump+ ID batches. It could still be a transfer if it were to be moved to Saikyo Jump, change its publication schedule to bimonthly, and hence don't need IDs for a long time. Still, I see it as something so unlikely it's just random theorizing.
As for Bone Collection, series is dead. Like, 100% sure here.
The remaining IDs are probably errors, since the first 2 left unknown IDs were the spot Neverland usually had and it makes no sense for it to be there, and the one after Ayakashi is also pretty random? As long as the series doesn't randomly get 2 chapters in the same issue which I highly doubt.
Also don't wonder too much about Neverland's One-Shot being in one of those IDs, since those are usually saved in a higher ID number (could be around 77xx or something).
