Some strings are still untranslated while Crowdin says it's 100% complete for the target language (Japanese)
It happens on all languages. Note "Dashboard", "Sections", "Strings":

Likely it's because they are defined in the UI files:

ℤ rg "\"Dashboard\""
src/widgets/Dashboard.ui
4: <widget class="QDockWidget" name="Dashboard">
