Natively syncer appears to be malforming some Amazon series URL

Description of your request or bug report:
There’s an odd sync issue with Las crónicas lunares | L28; the books are apparently only available physically, but do have an Amazon series page. When that series page is fed to the Natively syncer, however, it modifies the URL in such a way that when I visit it, only some of the books are shown on the series page, meaning Natively can’t update with missing books.

Pictures and URLs to explain better:

(Original Amazon ES URL: https://www.amazon.es/-/en/dp/B08PDN21PF?binding=paperback&ref=dbs_dp_rwt_sb_pc_tpbk)
Book 4 is shown on Amazon series page:

(Natively URL used for syncing: https://www.amazon.es/dp/B08PDN21PF/)
No book 4 shown on Amazon series page:

So, doing the ‘on hold’ user report which links here now.

Yeah, this sometimes impacts Spanish / German / French. We default to looking at the kindle edition (or, if nonexistant, the paperback) which often times is the best edition to look at.. however it’s not always the right one. We could fetch each one, see how many volumes each has, take the one with the most volumes and then sync that way… but that still wouldn’t cover all the cases (i’ve seen cases where the series list different volumes, neither one fully listing all the volumes).

So, i think we just should rely on moving these series to manual series. We do an initial import, block the syncing and then either users request the additional items or the librarian proactively adds the books via their admins.

I don’t think this is a bug - So i’m going to mark this as solved now.
