Someone posted possible packaging issue?!

I read in a post here last night while going through the faint line pics, and one was a pregnancy test that is supposed to have (I) (I) lines for pregnant.. She asked if it could've been a packaging problem because her line was horizontal for the results, while the control line was still (I) vertical! I can't find that post now, but it just happened to my test too! I'm 8dpo...anyone ever hear of this?! ?
