patch of hair won't wave

so I've been at this for abt a year and some change and this has been a more recent thing, this patch of my hair will not mesh the same as the other hair when washing & styling or just brushing & ragging. idk why because this hasn't been the case a year before, am I doing smth wrong? It's probably because this is my 2nd swirl from what I'm told but this wasn't like this a year ago.
