Can you clarify something -
Was the original test with VSE 8.7i + Storage add-on, or was it with VSE 8.8 + Storage add-on?
The scanning architecture of these two solutions is markedly different; just need to be clear on what you're testing with.
Also, to ensure a valid test, be sure that you are not generating the Eicars from the same server where VSE for Storage is installed.
The original test is with VSE 8.8 patch 1 + Storage 1.0.2.
The Eicars were not generated from the same server where VSE for Storage is installed.
That being the case, I suggest contacting Support with these test results. We may have some hotfixes for you to install (post 1.0.2 release), see if the issue remains - and if so, investigate it further with you.
