I had the same problem. It has to do with the way you filter the report.  

It all depends on how you Filter or what perimeters you set for the report.

Go to Reports

Transaction Detail by Account

Top Right says: "Pivot", "Group by", "Filter", "General Options", "Columns".

Select: Filter   

3 Choices show up:  "Filter by", "Options", "Value"

Click Filter by and choose "Memo/Description"

Click Options and choose "Contains"

The report should now show what has been written in the Memo and Description fields that were placed in each transaction.
