Mhh, I can only check your end of sept 16 rack, because the others are private and that looks fine for me.
It has a lot of modules so I am not quite sure ;)
Are the private ones even larger? Does the screenshot feature works for you at small racks?

does the screenshot default to a particular order of saved racks perhaps?

If you create a new one the older will be overwritten.
If you still see the older one that typically is cache issue. Maybe a proxy server?

You can try to create a screenshot from the Command Center, the loupe icon does this.
