Center group on the desktop

Hello, guys! I have a weird problem.
I have a group that contains a fixed group -> repeating group -> image. These elements are parents and children. I center each element, but it does not center them completely. No problems on the mobile buy on the desktop it is several pixels left. https://youtu.be/1j-Gvm9fgzA

I also have another group(hidden on the video) that has the same responsiveness parameters and it centers great. It contains of an image inside a group.

Any hypotheses?
