Problem with backup after canceling it

Damn, I have the same issue too.

Running 2.0.3.5_canary_2018-04-13 with Minio and B2 as backend.

1st, I had:

Errors: [
    2018-04-29 20:01:21 -04 - [Error-Duplicati.Library.Main.Operation.TestHandler-FailedToProcessFile]: Failed to process file duplicati-20180430T000000Z.dlist.zip.aes,

I tried to repair DB, with the error still happen. But at least the backup was still working.

Then I tried to rebuild the DB, but now the backup failed each time with:

Unexpected number of remote volumes marked as deleted. Found 2 filesets, but 20 volumes

Any idea on how to fix this issue ?
