Why is there only an edit and review/accept link, but no reject change option, for previously entered translations? Or if there is such an option - where would it be located? Couldn't find an undo option on it anywhere.

What are you talking about?
When I was trying to blank/undo the invalid translation earlier:
https://www.mediawiki.org/w/index.php?title=Developer_hub/nl&diff=prev&oldid=3582906
I deleted your wrong edits on Translations:Developer hub/Page display title/nl and Translations:Developer hub/67/nl.
To nominate a page for deletion, use {{speedy}} or {{delete}}.
About the translation interface, ask on Project:Support desk or request on Phabricator.
