No attachement mark shown

I noticed some malfunctionality in web client. E.g. when I open invoice screen and filter the data I do not see any “attachement sign” in the section header.

On the other side, when I open it without filtering, typically with all items displayed, I see the “attachement sign” perfectly in the section header.

What platform version are you using?

Then we have to find out. Can you please give us exact steps on how to reproduce it (from the time you log in to the web application)? Thanks.
