Title Correction Not Working

Hello.

I have trying to correct the title of my short film by changing the small-capped "in" with a capitalized "In". However, the standard means of correcting the title has been automatically rejected:

I would prefer that the word "In" be capitalized since it is used as an adjective.So the title reads as "A Variation on the Old In 'n Out"
