The UI probably needs some extra hints to guide users on this, but essentially you need to split those put-docs entries across separate transactions (otherwise the first version gets ~dropped, see also): XT Fiddle
Alternatively, you could also specify distinct valid-times for the entries, e.g.: XT Fiddle
The ‘+’ button appeared to be disabled (it renders kinda greyed out). I had executed the two transactions one after the after, but editing and running each time.
Using the ‘+’ and adding the second transaction that way worked.
