Configuration Confusion

 

Hi All,

 

I'm having trouble with this part, specifically the configurations. It's a simple tubular weldment using 3d sketches, however if I edit one of the configurations, it ends up breaking the other 2, pulling dimensions from who knows where. I can't seem to find a solution, and I would like to keep these parts in one configuration.

I'm using Solidworks 2020 Professional

Any help would be appreciated.

 

Thank you!
