Error message at Already Read Stats page does not work on merged works

[onnotasler]

I got an error message telling me that "3 works excluded due to missing data" from the "Most Read Authors" section. I assume it should tell me which books are missing (because that is what it does with the other stats), but in this case, I only get question marks:

(????) by
(????) by
(????) by

Upon looking into it, I saw that three of the books from my list had been merged and remained only as placeholders. Once I removed the books from the list and added them anew, the stats showed up correctly.

I doubt that this behaviour is intended, but it is mostly a cosmetic problem.

Proposal & Constraints

I do not know how this problem could be technically solved, but at the moment, one can either clean the database or constantly render list entries unusable.

Stakeholders

Almost anyone who uses any list.
