Dashboard, Storage status incorrect after check failed "Missing Chunks"

Please describe what you are doing to trigger the bug:
Using Duplicacy Web Edition 1.5.0 to run daily backup to local storage, prune local and B2 storage, check local storage, copy to B2 storage, check B2 storage

Please describe what you expect to happen (but doesn’t):
Expect correct status to be shown on Dashboard and Storage pages.

Please describe what actually happens (the wrong behaviour):
B2 storage check failed “Missing Chunks”, but Dashboard shows “All successfully checked” and B2 Storage shows “All referenced chunks exist” status.
