is the source set correctly for the group containing the details is each cell? I assume each row’s contents are grouped in a group of type Autopart, but do you have any smaller embedded groups? are the part name: value grouped together for example? check the debugger it can tell you where data is not being fetched
if it shows as empty, then data is not being pulled and data source needs reviewing,
if is shows correctly then the problem is in layout or privacy, and e know it’s not privacy so it may be that text layer dimensions are too small to show the text.
Hope this helps. Can’t really think of anything else without seeing the editor so I hope this is enough.
