First of all, I went onto my profile and saw this:
[you must login to view links] The Pokémon in my sixth slot was not showing up on my profile, even though you can tell I have six in my party from this screenshot.
Second, this is my team before logging out:
[you must login to view links] I circled the time for proof, and this is my team after logging back in:
[you must login to view links] again, I circled the time for proof, so you know I'm not making this up. It started about a week ago, and I found out about the not showing up when I logged out to log into my other account, and then logged back in, and the profile glitch I found when I went to look at my sig. If this can be fixed, I'd be really happy.

Click where it says "here" in the yellow.
Remake your team and it will be okay.

Okay. I'll try it. Thanks!

In case you don't know where that is, it's in the "Your Pokemon" section in the top left.

Thanks. I worked! ^U^

I'm not really sure what happened but I know someone who will I'll ask him about it. Just in case I don't have time his username Is 1Dogzilla and you can ask him

The problem was fixed already, but thank you.

you have to replace your whole team to fix it lol its happened to me numerous times especially when you have a loaned pokemon and they take it back while its in your team itll do that as well

Thanks, I got it.
