In 1.3 test version (at least on Windows), open Object > Symbols...

In the right pane there is a drop down menu that says Current document / All symbol sets / etc. with these two strings in English only.

1. The "Current document" string appears to be missing from the .pot file.

2. There is one "All symbols set" string already translated, but probably it belongs to other menu (?) as it has no influence on the one mentioned here.

Checked with de and it also – no difference.
