When I insert a page number field, I get the words "page numbers" instead of actual numerals

[SeriouslyThough]

Libre Office 5.4.3.2

The document has two states concerning the TextFields: Showing information about the field types (“Field Names”) or showing the value.
The state of the doocument insofar is switched with Ctrl+F9. You can also go >View>Field Names.
