I just had this problem and was not able to find the answer anywhere online before figuring it out myself, so here ya go.
Premiere pro is not aligning to center properly, making centered graphic elements (like my text here) look like the pic below when hitting the align tools to bring it to "center" horizontally and vertically.
All I did was start using the position settings under "FX Motion" instead of the align tools, and it cleared this weird bug.
Maybe this was a weird bug in Premiere. It certainly is not uncommon to have something weird happen to you when using this program, but I figured if I had this issue, I might be able to help someone out who has a similar one.
If you want more tutorial-style content like this, let me know! Thinking of doing more of it to help out the community where I can as I'm doing a lot of learning at the moment myself.
Thanks for reading,
Tom.
