Error in English string?

There is an English string that I find strange in LibreOffice 4.4:

https://translations.documentfoundation.org/da/libo_help/translate/#search=Transpar&sfields=source,target&soptions=exact&unit=28584506

The text for this string says

"Choose <emph>Format - Chart Wall - Transparency</emph> tab (chart
*documents*)"

Shouldn't that be:

"Choose <emph>Format - Chart Wall - Transparency</emph> tab (chart *objects*
)"?

As far as I know, there are no "chart documents" in LibreOffice, but there
are chart objects, and the text does apply to chart objects.

Okay, so there are actually *19 places *where these mysterious "chart
documents" are mentioned:

https://translations.documentfoundation.org/da/libo_help/translate/#search=hart%20document&sfields=source&soptions=exact

(I search for exact phrase because it is faster, so I left out the c/C in
"chart" in the search).

I wonder what is right. I just never heard of "chart documents", and I
cannot find any in LibreOffice 4.4 when I look around. Under File | New… I
cannot create a new "Chart document"…?
