I have a big problem with my submission for Doctor Who.

My grammar might be a bit strange, but just bare with me.

Last year ago, when I was submitting the animators' names who were uncredited in the Doctor Who's episode called "Lux", it wasn't working. I've been trying to submit it so many times, it just starts not to work. It won't even get it in. The weird part of my submission is, when I saw one of my two credits for the "Lux" episode, they "actually" got in, but not the other credits that I've credited that weren't accepted. It took me half a year to get it in, and it feels like it's starting to have an error. Like, I don't think I'm having an error in my contribution, I think it's the Doctor Who's Lux episode credits bar that have an error in the site and it won't let me accept the credits to originally get in. I'm just trying to figure why it keeps doing this nonsense and I just need help, please. 

Here's evidence of my two credits on the full credits bar.
