When I tested on new feature at 4.0.4, I can not test restored recordings files purge policy.
Because I set some value at "Remove Restored Recordings Older than" value at purge policy.
But it reset when I move another configuration page.
So, I can not purge restored recording files.
Reproduce steps is here:
show the value which is set at step 3 in above steps. such as 3 at this example.
reset to 0.
Release : 4.0.4
Development team finds root cause of the problem in UI function.
It seems to be missing update stored value for this parameter.
The problem will fixed next release, 4.1.2 or so.
This is UI problem. So, API can set the value correctly.
Please use following API to change configuration:

Also, API can check current configuration.
