I've just purchased 12 NIVAC volumes (thanks to the sale discussed at https://community.logos.com/forums/t/104242.aspx) and noted that there were two "Resources Updated" notifications after download and while the volumes were being added to the library.
One at the beginning

One when they had all been installed

I didn't see any count from 1-12 but I could have missed it.
Is this intended behaviour?

PS: I seem to remember a reference to this earlier but can't find it.
