word "Abstract" missing in word file, but present in PDF

hello @opoudjis in the front matter of the document, there is the Abstract and at the start of that the word "Abstract:" is in bold. however in the ms-word file, that word is missing.

the current version of metanorma was used in the generation of this file between the June 3 and June 10.

details are shown here: https://github.com/Spatial-Web-Foundation/SWF-Corpus_and_IEEEP2874/issues/1616

if you can check into this at your convenience that would be helpful. thanks

Was inserting "Abstract:" header when the document scope was being presented as the abstract, but not when a discrete abstract was included. Not seeing a good reason for the distinction, getting rid of it.
