That's good

I'm a bit confused by this statement. This patch did need to be updated for firmware 4.18.13737 but, as far as I know, it only affects a very small part of the GUI. It shouldn't (now or ever) have affected the book lists and TOC entries.

Carefully compare the code you are using for your version of this patch with that in the copy of nickel.yaml in the standard download pack of kobopatch.

The word "bug" implies "avoidable, fixable error". It is currently neither avoidable nor fixable. After a full reboot the Kobo only has access to a very few built-in fonts. You have to force it to load all its sideloaded fonts. I discuss the simplest workarounds here in the previously linked thread.

You can use New patch - "Custom page navigation scrubber" detailed in post #3 of this thread to customise this font.

-------------------------------------------------

Whilst all of the above should improve things for you - in a rather piecemeal manner - there is a potentially "better" option you might like to consider.

It is discussed in the kobopatch users & non-Kobo-supported languages thread I linked earlier? Look for the posts discussing using a font editor (e.g. FontForge, TTFEdit, Type Light) to help you internally rename your 2 chosen Noto fonts to Georgia/'Avenir Next' before sideloading them.

This will give your Kobo GUI a complete overhaul and you won't need to repeatedly customise font-family in multiple patches. You will still have the same problem after a power-off/reboot but this option will survive a firmware update without needing to be re-applied.
