Hello, this is actually documented in the release notes. This happens when you are using network backup mode, and backing up VM that has existing snapshots. You should either change backup mode (other backup modes consolidate snapshot data during backup), or remove snapshots from the source VM; and then backup the VM again. After that, FLR will start opening latest VM state. I would advice to remove snapshot from the source VM in all cases, because it is generally considered bad practice to run VM of snapshot.
If you need to restore files from the current backup, you would have to restore entire VM, as for your current backup FLR will always open VM state before the snapshot was taken.
