You probably have some "Filter" set that is preventing you from getting any results. In the "Filters" section, make sure to clear out the: Client, Project, Task and Expenditure files (they should say "optional"). If they have something in them, then tap on the grey "X" to clear out the field. For any of the filters below that, you may need to change them to "Any" to determine which one of them may be preventing you from seeing results. Also double check your Start and End dates.
