Description:
The cross-reference of the type `Above/below` is not updated properly.

For example, in the attached document `Subscription Agreement.docx`, on page 51,
- it has the content: `8.	Paragraph number = 2.1 above`

Here, `2.1 above` is the cross-reference of the type `Above/below`.
It means, in MSWord, the Field options of the cross-reference include:
: `Relative position of paragraph`
: `# of paragraph in relative context`

But if you open it in the LibreOffice, `2.1 above` becomes `above`.

On page 51 of this document, I added multiple examples of the cross-reference of the type `Above/below`.
You can check the paragraphs containing cross-references below the text `Above + “above/below x-ref” functionality`.

Steps to Reproduce:
1. Make a document in Windows MSWord containing the cross-references of the type `Above/below`
2. Open it in LibreOffice

Actual Results:
The cross-reference of the type `Above/below` is not updated properly.
`2.1 above` becomes `above`.

Expected Results:
The cross-reference of the type `Above/below` should be updated properly.
`2.1 above` should remain as `2.1 above`.
