Columns randomly nesting within them selves

I Just thought I would spin up a local build to play around with putting all the meta boxes into a plugin.

I seem to be having an issue with how the column is being created, If I make a line of columns equal to 12, they some stack inside of each other randomly, and if I refresh the restack in a different pattern.

I don’t have this problem on my live site and I have tried the normal deactivate everything to eliminate any issues but even with only metabox plugins activated it still does this weird behaviour.
