Mediacache API. Cmd flushAndForceItemFromCache destroy itemname

If I send as example every hour the api command flushAndForceItemFromCache for every Asset with foreach while from http://127.0.0.1:8087/v2/servers/defaultServer/vhosts/defaultVHost/mediacache/stores

As example with a filename: gcp/mc-11-bucket/archive/d840b4e5b58cf1e6d3ee832e15fe8d2c.mp4

curl -X PUT -H 'Accept:application/json; charset=utf-8' -H 'Content-Type:application/json; charset=utf-8' http://127.0.0.1:8087/v2/servers/_defaultServer_/vhosts/_defaultVHost_/mediacache/stores/actions/flushAndForceItemFromCache?filename=gcp/mc-11-bucket/archive/d840b4e5b58cf1e6d3ee832e15fe8d2c.mp4

The itemname will append random chars to my mp4 path:

Looks the last result in above code with my example. The itemname is now corrupt. But it looks like not on all, see (gcp/mc-11-bucket/archive/9bc3012bcd225dcfaafdaa04608777d3.mp4). This looks fine. All other destroy the item name and can’t anymore remove from mediacache!

Urgent: Every time I call flushAndForceItemFromCache Wowza again and again append the random chars on the itemname. If I call it 20 times, then wowza append 20times the random chars.

After first call:
{
“success”: true,
“message”: “Forcing gcp/mc-11-bucket/archive/be89ed31931931c97464b5d8fd3178a7.mp4c5991d0b-1ec2-4397-b069-fb772cac27d7 to flush immediately”,
“data”: null
}

After second call:
{
“success”: true,
“message”: “Forcing gcp/mc-11-bucket/archive/be89ed31931931c97464b5d8fd3178a7.mp4c5991d0b-1ec2-4397-b069-fb772cac27d7b2f7a262-e354-4c6d-b855-7b9378eddecd to flush immediately”,
“data”: null
}

After third call:
{
“success”: true,
“message”: “Forcing gcp/mc-11-bucket/archive/be89ed31931931c97464b5d8fd3178a7.mp4c5991d0b-1ec2-4397-b069-fb772cac27d7b2f7a262-e354-4c6d-b855-7b9378eddecd2ddc4ea6-ad81-4a9b-ac65-a3b980ec8147 to flush immediately”,
“data”: null
}

And again, and again…

Anyone read this and can answer?
