Although the field values aren't getting stored, you have said that
you are able to *see* the custom fields displayed in the tiddler
editor (and, presumably, rendered in view mode as well, though without
any stored values that might be hard to tell).
This means that TaggedTemplateTweak is correctly selecting the custom
JournalViewTemplate and JournalEditTemplate based on the 'journal'
tag.
So, the problem must lie is some other plugin... or interaction
between several other plugins. So... what plugins are you using
(other than TaggedTemplateTweak, of course)? Also, try to eliminate
some possiblilities by constructing a simplified test case document
that reproduces the problem using the absolute minimum number of
plugins and customizations.
