Missing "from" translation on Calendars

I keep getting this weird thing when I look at the observations for a particular day from my observation calendar. This is on Google chrome on a mac.

Seems like it’s happening when I check observation calendar of other users too:

Don’t know what’s up with this but maybe @kueda does?

That looks like the same problem as there was about a month ago with missing translations.

Two steps forward, one step back. I removed the translatable string from because it’s basically impossible to translate out of context in most languages. I thought I fixed all uses of it, but I guess I missed one. I’ll patch this up.
