Unable to import data again after importing once before even after deleting.

[Savasdotexe]

Describe the bug Wanted to merge data logs from external/manual readings previously done so I exported then added the logs manually csv file, but noticed that some were not appearing.

To Reproduce Steps to reproduce the behavior:

1. Go to top right menu (...), export csv file. You should have some user data/readings.
2. Delete all logs/readings manually by going to Table > select reading, bin icon.
3. Go back and Import same file (no need to edit)
4. See error (notice no data exported), or repeat process from step 2 to reproduce.

Reproduced with latest dev version: ???

Expected behavior Should be exporting fully the entire list even after deleting.

Additional context I was able to resolve by deleting app data/clearing cache.

Debug log Attach a debug log (see Settings -> About -> Save debug log to file) that is captured while reproducing the issue.
