Possible content loss in 1-item (not also bulk) item transfer to another db

[Spliff]

I don't know why this is so, but more often than not, in fact in more than 50 p.c. of cases, when I cut just ONE item from db a (^x), then paste it into db b (^v), the item's content is lost, i.e. the content pane remains empty. (I have observed this over many months.)

Thus, I have to visually check, then get the content from the discarded item in Recycle Bin of db a (^a, ^c), to put it "manually" into the target item in db b.

This prevents me from automating bulk transfer from my inbox db to the thematic target db's, fearing data loss; instead, I do it manually, then checking visually the first, the last, and some item in the middle of the bulk for data loss; on the other hand, this visual bulk check is always negative, i.e. in bulk transfer, I have never observed any data loss, just, and then regularly, with transfer of just a SINGLE item, from one db to another.
