They (KUAL Booklet/coplate) shouldn't clash, but if you mix 'em up, yeah, I'd do a restart to avoid weird caching artefacts
.
In any case, that should have no bearing on whether you actually *see* the KUAL 'book' or not, unless your database has gone seriously wonky.
Do you actually see a "KUAL.kual" file in the documents folder when you look at it over USB?
(And, yeah, RP/CRP doesn't support those devices, so, that's to be expected
).
