I can not get the mitered ells to come in correctly.
I have added the data table, and updated the piping spec.
the fitting comes in with all the right data. it is just not displaying correctly

What happens if you lengthen the legs? It looks like pipes are interfering with each other as-is. Even a conventional ell would fail like that.

I get the same results.
just longer legs.
not even the 5 segments

Tha looks like a units mismatch to me. Check the catalog properties to make sure it is English/Inch and not Metric/Inch.

Here is a screen shot.

Verify the catalog units from here :

Edit to add, I created a mitered elbow using your dimensions for 60" worked fine on my imperial catalog/prj
