Pulling my hair out; CSS problem?

[Miscreants]

A good Sunday to everyone! Hello! I have been working on this project for a while now. A proffessional designer I had hired said my problem was an "advanced" problem. I'm thinking that this is a CSS offsetting problem and I have no idea how to fix it.

For some odd reason, whenever I generate a number on my HTML code, the first number generates properly. If you click that same number again, instead of remaining centered it offsets to the right - I have no idea how to fix it and I have very, very limited skills with HTML as it's not my primary area of study.

Also, when I try to move a generated number as soon as it's dragged, the number automatically "jumps' to another position, which isn't supposed to be happening. From what I have come to understand, this is a CSS problem.

Can anyone with knowledge of what is happening point me in the direction that I need to go in order to fix this error.

Anyone who would like to assist can see the problem(s) happening in real time, here:

I have also attached some screen grabs if you choose not to head to the 'problem area". XD XD XD

Have a great Sunday, everyone!
