Can not reset app. – Pocket Expense Pro - Personal Finance Assistant Review

I’ve had to delete all data and restart from scratch and the app somehow remembers all past data that was deleted. How to i delete the duplicates entries from past resets? Reason for the reset was because the app would remember an entry and once I deleted it, it would come back. Having the identical issue.
