I was looking at [
your list] and noticed that I have both GTAV and JC3 installed too. Both apps do show the space used.

Therefore we can't blame it on the setups or the apps themselves. Plus you have a huge list of consecutive apps with no space which is different from myself (1 out of every 8 or so apps for me are missing space used).
What's weird is that for me, both JC2 and JC3 show the same space and date, even though they should be completely different. I'm sure JC2 is smaller and it was definitely installed a few years back. I also notice that alot of the dates are 4/30/18, which is
probably when I installed the big April Windows Update. Yours is different.
I personally think Windows is just buggy when it comes to this.
Have you looked at the registry that sunder25 listed? I couldn't find JC2 or JC3 listed there, I'm sure they are somewhere else in the registry. I did see Dishonored (and it's 12.0gb).
Do you see "EstimatedSize" listed for most of your apps in the Registry, even the ones that are missing their "space used"?
