Rather Specific Issue (Prank?) With Custom Pikik

I wasn't really sure where to post this, as I'm new here, so I hope this is right. Basically, I got a Pikik app from a developers group chat online, and I just noticed an obviously intentional problem. If you were to type only "Hai" in a message (which I do more often than not) and send it, upon sending, will change to "I LIKE TO EAT ****". There's a similar problem with "hai" instead of "Hai", but I'd like to keep this thread somewhat family-friendly. Here is a url for the apk on my Dropbox:
dropbox.com/s/81rxhk7ftjocmf6/nhmgedhydrhftc.apk?dl=0. I'd love it if someone could fix the issue and return a link to me, as I'm not sure how to go about doing this. Thanks!
