A Bizarre Issue

Firstly, I'm posting on my blog for the first time ever with my feet Mac! It's so clean and new and fancy. It even still smells new. ...I'm not weird! I've been wanting to post a new little piece of animation I've done but have run into a bit of an odd issue. Perhaps someone can help me with this. On Adobe Photoshop CS5, using the timeline to animate, and I've gotten this oddness:

Now, most of the animation is in 2s, and you can see most of the lower layers are all in line. One stops being displayed at exactly the point at which the next starts. Then at layer 56, for some reason, the images stopped letting me change their... display bars? To be 2 frames long. No no, they want to be about 1 and a half frames long. I don't know how or why they're 1 and a half frames long but no matter what I do I can't seem to fix it. I can't align them properly and it makes the timing look odd. I know at one point I realised the framerate was 30 fps and changed it to 25 fps, but surely that wouldn't matter? If anyone can help me with this I'd really appreciate it. Even Dave looked confused. No luck when googling the issue either.

 I might upload the animation I was doing later anyway, even missing these dodgy frames. As for my current targets... polish up portfolio, finish portfolio commentary, and then blast the handin with every single piece of artwork I can find that doesn't induce vomiting. Sounds like a plan to me!

 I'm really not this negative in person. It's the evils of Blogger getting in my head. Honest!
