Fields alignment from master-detail data?

I’m trying to display fields from master-detail data, but in my case the fields are getting stack together. Any ideas how could I fix it?

It looks like you have included the detail data as child relationships in the master objects model.  I’d reccomend setting up a separate model on the child object,  with a condition so that it only retrieves data where the master ID is the ID on the primary model. 

Then you can use a table component to achieve the same UI you are attempting with the field editor, and you will get a very specifically defined row for eacy record. 

Look at this tutorial for more details.
