Why is "assault" flagged as profanity?

Games Halo: The Master Chief Collection
1

I tried to use it in a map description. The map would not save until I changed it to “battle.” Why?

I think its because it contains the word “donkey”. You could rename it to Ashault ?

Like 'Donkey’ault

See what I mean?
