Merging PDF's with multiple pages, title only applied to first page in footer

[Snowflake6]

I'm merging a set of PDF's, that usually is only single pages, but occasionally will have more than one. I'm using the command:

sejda-console merge -d . -o temp.pdf -t doc_titles --footer

And that gives me a single PDF that has a table of contents using the embedded Title field in each PDF and each page marked with the same Title. But only for PDF's with single pages.

If I try this and happen to have a multi-page PDF in the merge, the second and subsequent pages of the multi-page PDF are marked in the footer with the File Name rather than the Title.

Is there a setting i'm missing?
