No Details Under Subassemblies For Opportunity/Quote

This is stumping me. We have added a subassembly in a quote and have selected get details but none of the details appear to be visible. You can see in the picture below I’m not getting anything in the tree, but I’m showing there are actually details in there. If I try to get details again then I get an error stating that “Details already exist, use the AppendDetails method instead.” Any idea how to get the tree to display properly? We have tried removing all details. We have tried closing out of Epicor, clearing cache, trying different subassemblies. Everything short of creating a new quote.
