Okay, I sent a request to support.
This is the response:
"Indeed, the newest ones, marked only for Analog Lab V, won't be compatible with Analog Lab 4 as they are based on the latest versions of the instruments."
So, apparently the ones listed as Analog Lab V will only work in Analog Lab V.
I think the others will work in Analog Lab 4 (and maybe in all earlier versions of Analog Lab?).
