I completed one recently that was v2017 to v2020 and the masking allowed them to print.
Couple of things I did notice that may help...
1) Preview did not work for all of them. Some had to be printed regardless of mask update.
2) Printing as a group, some would not print. Printing individually all would print fine.
No idea why, just a couple of work arounds that I found could get them through the process. Hope one of them might help.
