It's a known issue, in the top post (emphasis mine):
NIGHT VISION: There are parts of night vision that still need to be fixed, like night vision tokens overlapping and animated tokens having a ghost like effect on the gm layer. (1) [STATUS: IN PROGRESS]
Good to know this issue is still present; I'm curious as to what they've actually fixed compared to when I gave this a go around September of last year. It seems nothing's been done since the last time they wanted to sunset LDL.
Speaking of pre-existing issues, here's one I posted about back then in the bug thread that's still present:
Bug: Dim Light from a token causes night vision on other tokens in the radius to be darkened
As the title says when any token with night vision passes through an area of dim light projected by another token the night vision gets darker.
Repro steps:
1. Create a token with Night Vision (example has 60ft radius)
2. Create a token that emits dim light (example emits 20ft of bright, 20ft of dim but same happens on 40ft of dim)
3. Either observe through the Night Vision token's controlling player or via Ctrl + L as a DM
4. Move Night Vision token within dim light radius of other token
5. Observe darkening of vision from the dim light
Here's a pair of visual examples:


Effect is even more noticeable without the Night Vision token set to "dimming"; the night vision token has no tint either.

Also found another bug while showing this one off:
Bug: Viewing a token's vision using Ctrl + L prevents that shortcut being used on another token
So if you select one token, press Ctrl + L to see what it can see, then directly select another token and press ctrl + L the vision doesn't swap to see from the new token. Selecting any other token without deselecting all tokens will prevent the vision from being shown; you will still see the vision of the original token until all tokens are deselected. The other tokens selected after the first token may appear through darkness if not visible to the first token.
As a note, I believe this wasn't the case in September of last year. Back then you could simply swap between tokens without deselecting beforehand; either that or I'm confusing this with the functioning version of this in LDL that does swap the vision when selecting a different token and pressing Ctrl+L.
Repro steps:
1. Select a token, press ctrl + L
2. Select a different token, press ctrl + L
3. Observe vision not changing but token may appear through darkness if not visible to the first token selected.
