Is there a max number of expenditure types in iexpense?

 We're on 11.5.10.2 and it seems we aren't able to see more than 145 expenditure types in the dropdown list. If we import the expense reports and submit the expense report immediately the expenditure types are ok, however if the expense report is imported and saved, the expenditure types that are alphabetically at the end of our list the expenditure type disappear when you save the expense report and try to update it later. If you key the expense report manually, you can't even see/select the expenditure types that are at the end of the alphabetically ordered list of expenditure types.
