I have not tested if this also happens on other pages that use tabs.
Example:
Go to https://mangadex.org/group/6bd61af7-e253-4fe5-90df-e958edd7ac52/harribel-group
Switch to feed and go to page 2
Switch to titles
No data found, because it's requesting page 2, when all titles fit on one page...
I appreciate your scanlations, bit it's a tiny bit ridiculous if the second chapter already has name change corrections, especially when they were uploaded at the same time...
I feel this bug was already discussed in V3, and fixed at some point.
Manga with Oneshot and numbered chapters mixed sort the chapters differently between manga page and reader, e.g.: https://mangadex.org/title/8cd657d2-fa8c-4927-b884-44952fe5fbd1/my-cute-cousin-always-gets-her-way
