Froza Motorsport 6 Apex download problem

I was trying to download Forza Motorsport 6 Apex it said it was in 21.9GB in size but i read its only 18GB. I left it over night to download and when i woke up it was going up more than the size promised
e.g 22GB of 22GB 23GB of 23GB and so on. now its at 27.30GB of 48.84GB. I tried deleting its location C:\Program Files\WindowsApps\Microsoft.ApexPG_1.0.6.0_x64__8wekyb3d8bbwe but it said that the location dose not exist.

Please help me with this problem,Thank you!
