KI installing windows store version 50+ gb downloading 2x

Trying to install KI definitive edition, have KI plain installed 6+ gb.
When I select to install definitive edition ( microsoft store win10 version)
the game wants to install two 50 gb + installs; if I either downloads are stoped,
both stop.
Is this normal or a glitch as the full definitive edition is approx. 57gb .
