WorkFolders - Access denied when File Screening is active

Hey,

We are testing Work Folders and for now everything works alright. We found out that we can apply quota so users will have 10GB space and it works, but we also we want to exclude some file types. We have tried to apply File Screening, but it seems it's not working properly.

server: Windows Server 2012R2
client: Windows 10 Pro 1803

File Screening: for testing - exclude *.exe only.

When passive: users can sync whatever they want
When active: users can't sync exe file, which is good, but also can't sync anything else, in the event viewer, for .txt file:

Event ID: 2114
Source: WorkFolders
Action: (FSP_EVENT_ACTION_UPLOAD)
HResultStr (0x80070005) Access is denied.
Hresult -2147024891

For exe file event looks okay, it just says that this file type is not allowed on this share.

I googled and couldn't find anyone having same problem.
