Storage statistics go missing

Bug
#1

Please describe what you are doing to trigger the bug:
I running a schedule including check. After completion click on ‘Storage’. Stats are ‘0’. This is inconsistent however and does not happen every time, or in a consistent manner.
Please note that check completes successfully.

Please describe what you expect to happen (but doesn’t):
I expect the statistics to be displayed correctly.

Please describe what actually happens (the wrong behaviour):
At the moment, statistics are 0 (see screenshots)

check completed successfully.

issue is somewhat similar to Dashboard, Storage status incorrect after check failed "Missing Chunks", but in my case the check does not report missing chunks.

#2

Statistics are stored in this file: ~/.duplicacy-web/stats/storages/<storage_name>.stats. Check the latest entry in this file to see if pruned-chunks and pruned-revisions are non-zero while all others are zero. If so, it means a prune job ran first and updated this file. If you wait until the check job finishes then all statistics should be updated correctly.

#3

On the 23/4 when it showed zeros, this data is in the file:

"2022-03-23": {
        "total-size": 6601364733952,
        "total-chunks": 967004,
        "pruned-chunks": 2617,
        "pruned-revisions": 28,
        "status": "Checked",

Today, it displays fine again, this data was written:

"2022-03-24": {
    "total-size": 6636798214144,
    "total-chunks": 971778,
    "pruned-chunks": 0,
    "pruned-revisions": 0,
    "status": "Checked",

In my current schedule I am running a check first, then all the backups and then a prune. Does the order matter?
