Certain doujin being hidden, even with no tags applied

[Slasly]

When searching for parody/character/tags a majority of items will sometimes be missing. Which seems to be at complete random, and it seems to change what shows up close to daily

Expected Behavior

1. Choose one favorited X doujin
2. Search Y tag from inside X doujin
3. X doujin shows up inside search

Current Behavior

1. Choose one favorited X doujin
2. Search Y tag from inside X doujin
3. X doujin doesn't show up inside search, even though the Y tag was taken from X doujin

Possible Solution

Steps to Reproduce (for bugs)

Context

To give and example
Recently I looked up doujin with [Macross Delta] tag and favorited one of the doujin, but then a couple days later when looked at the tag again, the majority of the titles are missing. Even the one I had favorited. But I can still read it through favorited, however if I click on 1 of the tags inside that specfic doujin, then that doujin will not even show up.
It seems to me like some things are being filtered, but I have nothing set in the [Manage Tags] tab and even tried the[Clear Tag Preferences], but nothing changed.
I also set the languange option to include all. However it still didn't show the majority of the items I see on desktop
I can still see the titles if I have the code for them, like If I look them up on the non-app version of Nhentai, but inside the app I can't see them

For for concrete example, the specifc one I favorited was #439775, which should show up either [Macross Delta], [mikumo guynemer]
or [messer ihlefeld] tags, but that doujin and most others are missing.
Even though I no tags are applied in the Manage Tags tab and the languange in the top right on frontpage is the worldwide/show everything
Also this is not just with these specfic tags, but a lot other too. Though this was the most recent example I know
