maybe you added this exception before switching the UI language. Some exception-texts can manually be changed, which of course are not translated then. Anyway, it should be possible to add the same exception again in the language and text of your choice, e.g. you can add "(Friday morning)" and the current text should be replaced (use the same start and end dates).
As to the song#, the current theocbase news mentions that some templates are not maintained at the moment.
In the printing dialogue you need to make sure that under 'Additional Options' (the blue bar) 'Display Song Titles' is ticked. You have to set this for midweek meeting, weekend meeting, and combo separately. They are switched off during a fresh install, but during an update they shouldn't be switched off. But it looks like that is what happened.
As for the translation: that is outside of TB. There is always a team of translators who do the local translations. If they do not keep up with updates, TB defaults back to English.
