Scansnap IX 500 not filtering Scans to DT3 Groups

I am using a Mac Catalina OS 10.15.3. My Scanner is using ScanSnap home 1.7.0. When I scan to DEVONthink 3 (“DT”), Scansnap opens DT and gives me a choice of Groups/subGroups in which to save the document. However, the document is only appearing in the Global inbox and I then have physically to move it into the relevant Group. What am I doing wrong, please? I never had this problem with DT2.

This is known issue of the last release and will be fixed by the next one.

Thank you Christian.
