Manga Being Added Twice on Import

[burnpsy]

Steps to reproduce

1. Already have a manga library, imported from MangaDex follows.
2. Add some more manga to MangaDex follows.
3. Attempt to import again.

Expected behavior

Usually this results in only the manga that aren't already in the library being added to the library in the app.

Actual behavior

Several manga get second copies added to my library. Removing one from the library will result in a second being added again the next time manga get imported from follows.

Also, they do not all seem to be synced up in terms of read chapters, etc. Most are, but some of them show for example 1 unread chapter on one and 6 on the other.

Are you importing from the settings or syncing from the library?

[burnpsy]

Syncing from library.

So I think your manga url's are wrong on the existing entries. Can you open the original manga, click links then click MangaDex, then open in browser and send that url.

do the same for the duplicate

This test got me the following links:

• https://mangadex.org/title/2022a7a1-59fb-446b-a37c-8bb3fed9a632
• https://mangadex.org/title/2022a7a1-59fb-446b-a37c-8bb3fed9a632

Which seem to be identical.

(I adjusted the duplicate to show the English title to make sure I didn't get the same entry twice.)

Hmm that is really weird. For clarification you did this by going settings -> mangadex -> sync follows from Mangadex

[burnpsy]

Yup, though that setting has been renamed "Pull MangaDex follows".

I had added 2 manga to my follows, pressed that button and oddly got notified that 94 manga added. Presumably the 2 new manga and 92 duplicates for what was already there.

[nonproto]

Can you send me your backup on disscord

[nonproto]

Actually if you remove the duplicate, then search in browse for the manga does it show it is in library or no?
I think somehow your library is in a weird state just trying to narrow it down.

[burnpsy]

For one manga with a duplicate I tried that and it was still noted as being in my library when I searched.

So I tried the opposite. I searched first, selected a manga with a duplicate and then removed it from my library from that screen.

I ended up with one in my library and the search no longer saying the manga was in my library.

[burnpsy]

Honestly considering just wiping my library and importing a fresh one from MangaDex if it will resolve the issue, just not sure if I should do that before we figure out what the problem is.

[nonproto]

Go ahead and do that I am at a loss why yours got in this state
